# What is the frational equivalent of the approximation of pi?

22/7 is the older fraction approximation.

355/113 is a newer fraction. Notice it uses easy to remember numbers 113355.

Neither one is exact because Pi is an irrational number. That means it can not be expressed as a fraction or a repeating decimal.

### What is the fractional equivalent of the approximation of pi?

That depends on how precise you want the approximation.

### What fraction is the equivalent of pi?

pi is irrational so there can be no fraction that is equivalent. 22/7 is often used as a simple approximation.

### What mathematical principle is equal to 3.14?

That's not a "mathematical principle", it is an approximation of the number pi. That's not a "mathematical principle", it is an approximation of the number pi. That's not a "mathematical principle", it is an approximation of the number pi. That's not a "mathematical principle", it is an approximation of the number pi.

### What is an approximation of pi?

Think of pi as infinity. It never ends. You might mean "3.14" as an approximation of pi, though.

### What is the approximate equivalent of pi?

The approximation of Pi is 22/7 and the most used form is 3.1416 (rounded up). To 30 decimal places, pi is : 3.14159 26535 89793 23846 26433 83279

### Why value of pi is considered 227?

22/7=3.14286 Which is a fair approximation to Pi, but 355/113 =3.14159 and is a much better approximation.

### What is pi times 22 over 7?

You can only express this exactly by leaving it as is: 22/7 times pi. If you want a decimal approximation, use an approximation of pi, for example. 3.1416, and do the calculation on a calculator.

### Does pie equal to 22 over 7?

No, 22 over 7 is not equal to pi, but is instead an approximation of pi, as it only gives you 3 digits of pi, the rest (after 3.14) in 22/7 are wrong. Pi is 3.141926......... And goes on forever, meaning that a fraction such as 22/7 will never be fully equivalent to pi.

### What is the numerical equivalent of pi?

A1. Pi is an irrational number. That means that it cannot be expressed as a ratio. 25/8 is a good rough approximation, as is the more common 22/7. A2. 3.1415926535897932384626433832795 usually shortened to 3.14

### What is the entire decimal approximation for pi?

To have an "entire approximation" in itself is an oxymoron. We have to approximate pi because you cannot express the true value of pi as a decimal. It goes on forever. This is an invalid question. Pi is generally approximated, however, as 22/7 or 3.14.

### In math why does pi represent 3.14?

Pi does not represent 3.14. Pi represents the ratio of the circumference of a circle to its diameter. Pi is an irrational number. 3.14 is but the crudest approximation of pi. A better approximation is 3.1416. Still better is 3.14159. The closest approximation commonly used in real-world applilcations is 3.14159262. If anything, 3.14 represents pi, and represents it very imprecisely. As for why the term "pi" was chosen to represent this important concept in mathematics… Read More

square root(pi) is about 1.77245385. It is not a rational number so this is just an approximation.

### Is Pi 3.14?

Pi is the circumference of a circle divided by the diameter of a circle. 3.14 is an approximation of Pi. It is not possible to display the value of Pi. (See the related questions.)

### If a circle has the diameter of 3 what is the cirumference?

The circumference is equal to the diameters times pi. Pi is approximately 3.14, so just multiply 3 x 3.14. If you have a scientific calculator, it will probably include a special key to give you a better approximation for pi. The circumference is equal to the diameters times pi. Pi is approximately 3.14, so just multiply 3 x 3.14. If you have a scientific calculator, it will probably include a special key to give you… Read More

### Why does pi equivalent to 3.14?

Actually it isn't exactly 3.14 - that's only an approximation. It has an infinite number of digits, starting with 3.14159265... As to the "why" - well, pi was originally defined to be the ratio of a circle's circumference to its diameter (divide its circumference by its diameter), and that ratio was found to be a certain number.

### What is the formula for the diameter of a circle given the circumference?

diameter = circumference/pi (pi = 3.14159265 or 3.14 for rough approximation).

### What is the radius of a circle with a circumference 36 meters?

Circumference of a circle = pi * d d = 2r (i.e. the radius * 2) Therefore the radius = (Circumference/pi) / 2 I will substitute pi = 3.14 (Note: this is only a loose approximation. Pi is an irrational number which is infinitely long. If you wish a more precise answer you should recalculate with a more accurate approximation of pi.) radius (in metres) = (36/3.14) / 2 = 5.732m (to 3 decimal places… Read More

### How do you get the circumference of a cicle knowing only the diameter?

circumference = diameter x pi (pi = 3.14159265 or 3.14 for rough approximation)

### What is the circumfeRENCE if the diameter is 14?

To get the circumference, you multiply the diameter by pi. The exact answer is 14 times pi, or 14pi, (where 'pi' is assumed to be π). An approximation of 14π is 43.9822964.

### Which is NOT a close approximate value of pi?

Nothing on the list provided with the question is anywhere near an approximation of (pi). Pi=3.14159. So any number that is not close to that is your answer.

### What is the closet fractional approximation for pi?

Pi is an indiscriminated boolean hypothinator, so it cannot be given a truely incomponential denominator. Therefore, as 1/2 = 2/4, Pi = 7/62626Pi That is pure gobbledygook. Since the questioner speaks of approximations, I presume (s)he knows pi is irrational. There is no closest fraction to an irrational number. No matter what fraction you pick, there is a closer one. Fractional approximations to pi are usually (not always) given as a decimal, so what makes… Read More

### How could you use pi to find your hat size?

If you divide the circumference of your noggin by Pi, that will be a pretty good approximation of your hat size.

That's an approximation of "pi", truncated after ten decimal places.

### Why was pi discovered?

So Marie Callendar's would have something to sell, NO SERIOUSLY! The Egyptians used an approximation of Pi in the 20th century B.C. and probably used it for construction and building. It is often important to know the circumference of a circle and it is Pi times its diameter. They may have been the first to discover it. A century later, the Babylonians used Pi. As time passed, the approximation they used improved.

### What is the diameter of circumference of 8 cm?

circumference = pi x diameter; diameter = circumference/pi = 8/pi pi is approximately 3.14 You do the math if you want an approximation (There is no rational answer to this question, only approximations.)

### Why is pi irrational and 3.14 is rational?

pi is an irrational number because it cannot be expressed as a ratio of two integers. In fact, it is a transcendental number, but that is not relevant here. 3.14 is a rational approximation to pi. It is not equal to pi.
