Wow, what a crappy answer you got.

Try this,

The most thorough list of pi tidbits that I have ever seen... because I WROTE IT as a consolidation of facts accumulated from around the internet.

I tried not to make it too mathy.

### Interesting things about PI?

Pi itself is a very interesting number. It occurs in many areas of mathematics, including calculus, geometry and simply arithmetic. Pi is an irrational number, that is it cannot be written down in its whole form. It has an infinite amount of decimal places after the original 3. It can be used to calculate the area or circumference of a circle. Area of a circle = pi*r^2, and the circumference of a circle = 2*pi*r…

### What are some fun facts about pi?

Here are two fun facts: 1) The exact value of pi is infinite. It goes on forever. 2) The figure pi is present in the base of the Egyptian pyramids although the Greeks had not discovered it yet. Erich von Daniken suggested help from space aliens, but it is now thought that the Egyptians used a measuring wheel which incorporated pi without the Egyptians knowing it.

### What value is pi?

To 8 places its value is 3.14159265. Pi is the ratio of a circle's circumference to its diameter. It's an irrational number; that means it can't be expressed as a fraction, or an exact or repeating decimal. Two convenient approximations are: Pi ≈ 22/7 = 3.142857142857142857142857... 1/Pi ≈ 113/355 (a very interesting curiosity with the first 3 odd digits!)

### What are facts about Pi day?

Pi day falls on the 14th of march every year, and is celebrated by people Worldwide. Since March is the the third month of the year this means, it's the 14/3 i.e the three most recognised digits of pi. Interestingly, with the aid of computers, pi has been calculated to over a trillion decimal places.

### How do you change radions to degrees and degrees to radians?

360o = 2*pi*radians or 180o = pi*radians Convert 7*pi/15 radians to degrees 1 radian = 180o/pi Therefore: 7*pi/15 radians = 7*pi/15*180/pi = 84 degrees Convert 84 degrees to radians 1o = pi/180 radian Therefore: 84o = 84*pi/180 radians = 7*pi/15 radians. Hint: pi always in radian and 180 always in degree. They are equivalents (not equal) to each other. To convert from radians into degree, first erase radian by dividing the given value by pi…

### Is pie linked to pi?

Sorry to break your heart, but no. Pi is just a number approximately 3.14 and a pie is a yummy pastry. However, if the pie is round, then the ratio between the circumference and the diameter is pi. If you measure from the edge to the center of the pie, you get its radius, and if you square that and multiply by pi, you get the surface area of the pie. Then you can multiply…

### Where in the Bible is there a possible indication of the value of PI?

The Wikipedia link that I posted has some historical information about Pi, including references to the Bible. Both of these [1 Kings 7:23 and 2 Chronicles 4:2] reference measurements of a round basin in front of the Temple, stating that it is 10 cubits across and 30 cubits circumference. This would imply a value of 3 for pi. The article is interesting, and it contains various formulas that have been used to approximate the value…

### What are a dozen or more facts about pi?

### Can you show me a ending sentence about paragraph on pi?

Write sentences the way you speak - just pretend you are telling this to a friend, and write down what you would say. What would you tell them about this topic? Look up some facts! How would you explain Pi to your friend? If you just start writing, you will be through with your assignment before you know it!

### What are facts about pi?

Pi is a transcendental number. It starts with the number 3! ---- How about that it is a never ending number....there have been contests to see who can memorize the largest amount of numbers included, and to date, the winner has been Akira Haraguchi of Japan, who claimed to have memorized 100,000 digits. However, Guiness Book of Records has not verified his ability, so the recognized winner is Lu Chao of China, at some 67,890…

### What is an irrational number?

Irrational numbers are numbers that cannot be expressed as fractions with whole numbers. They are generally roots (such as the square root of two) or constants (such as pi and e). They are interesting because they cannot be exactly expressed as decimal numbers because they never terminate or repeat themselves. an irrational number is a number that goes on and on for a long time like pi

### What are the facts about the pi symbol in mathematics?

Pi is the quotient of a circle's circumference divided by its diameter Pi Day is March 14th because 3.14 are its first three digits Pi is the 16th letter of the Greek alphabet and p is the 16th letter of our alphabet Pi is the first letter of the Greek word meaning perimeter Pi as a mathematical symbol was introduced by William Jones in 1706 Pi is an irrational number that can't be expressed as…

### What is the square root of pi when it is indirectly related to the negative coefficient of sin of cosine unless the Pythagorean theorem is used and divided by 2?

As certain as I am that this post is the work of a vandal, I'll try to play it straight nonetheless: -- (pi) is a number. Its square root is 1.77245 (rounded). Neither of these facts depends on anything else. -- The phrase "... negative coefficient of sin of cosine ..." is meaningless double-talk. -- The Pythagorean theorem has nothing to do with (pi). -- There is no such operation as dividing a theorem by…

### What are a dozen or more facts and features regarding the mathematical symbol for pi?

1 Pi Day is March 14th because 3.14 are its first three digits 2 Pi is the value of a circle's circumference divide by its diameter 3 Pi is the first letter of the Greek word equivalent to perimeter 4 Pi as a mathematical symbol was introduced by William Jones in 1706 5 Pi is an irrational number that can't be expressed as a fraction 6 Pi as a fraction is about 22/7 but not…

### Who invented pi 3.14?

This number has been known since ancient times, although we have arrived at more accurate values lately. Wouldn't it be interesting if, buried deep in the digits of pi, the human genome as it is now was encoded? It would be a very strange co-incidence, but given that Pi is an irrational number.... I don't about more "accurate", because it's been calculated to decimal places far, far beyond anything that can be measured, so after…

### What are a score or more facts about the mathematical symbol pi?

1 Pi is the value of a circle's circumference divided by its diameter 2 Pi Day is March 14th because 3.14 are its first 3 digits 3 Pi is the 16th letter of the Greek alphabet 4 Pi is the first letter of the Greek word for perimeter 5 Pi was first used as a mathematical symbol by William Jones in 1706 6 Pi is an irrational number which can't be expressed as an exact…

### Whats the area of a shaded circle with 90 degree angle?

The area inside a full circle is given by the formula: Area = Pi x r x r where r is the length of the circle's radius. However, the angle of 90 degrees is only one quarter of a rotation of a line about a point at its end, so the required area is one quarter of the full area. So the required area is (Pi x r x r) divided by 4 A fairly…

### What is a Three Pi Vise?

A geometric composition of three adjoined, circle-squaring right triangles where hypotenuse is that circle's diameter. Long side of each right triangle has length equal to a side of that circle's square. "Three Pi" of "Three Pi Vise" refers to the three adjoined right triangles, defined by increments of Pi; "Vise" refers to the symbolic Pi Corral (re: "transcendental" Pi) of this composition. Length of adjoined diameters (hypotenuse) = 2.0, sqrt(Pi), Pi/2, Pi(sqrt(Pi)/4) Integrated by constant…

### How do you work out the area if given the circumference?

Assuming the shape concerned is a circle, Radius = Circumference/(2*pi) and then Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi) Assuming the shape concerned is a circle, Radius = Circumference/(2*pi) and then Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi) Assuming the shape concerned is a circle, Radius = Circumference/(2*pi) and then Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi) Assuming the shape concerned is a circle, Radius = Circumference/(2*pi) and then Area = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
