# 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 numbers of pi. Another cool fact about pi is that it is always equal to the ratio of the circumference of a circle/its diameter. pi=c/d. Always true, regardless of how large or small the circle is. Have fun :-)

### 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 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 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)

### What was the answer to pi in the year 1989?

pi is not a question so there was no answer to pi - in 1989, before 1989 or since. pi is not a question so there was no answer to pi - in 1989, before 1989 or since. pi is not a question so there was no answer to pi - in 1989, before 1989 or since. pi is not a question so there was no answer to pi - in 1989, before 1989 or…

### What is the exact value using a sum or difference formula of the expression cos 11pi over 12?

11pi/12 = pi - pi/12 cos(11pi/12) = cos(pi - pi/12) cos(a-b) = cos(a)cos(b)+sin(a)sin(b) cos(pi -pi/12) = cos(pi)cos(pi/12) + sin(pi)sin(pi/12) sin(pi)=0 cos(pi)=-1 Therefore, cos(pi -pi/12) = -cos(pi/12) pi/12=pi/3 -pi/4 cos(pi/12) = cos(pi/3 - pi/4) = cos(pi/3)cos(pi/4)+sin(pi/3) sin(pi/4) cos(pi/3)=1/2 sin(pi/3)=sqrt(3)/2 cos(pi/4)= sqrt(2)/2 sin(pi/4) = sqrt(2)/2 cos(pi/3)cos(pi/4)+sin(pi/3) sin(pi/4) = (1/2)(sqrt(2)/2 ) + (sqrt(3)/2)( sqrt(2)/2) = sqrt(2)/4 + sqrt(6) /4 = [sqrt(2)+sqrt(6)] /4 Therefore, cos(pi/12) = (sqrt(2)+sqrt(6))/4 -cos(pi/12) = -(sqrt(2)+sqrt(6))/4 cos(11pi/12) = -(sqrt(2)+sqrt(6))/4
