# What is special about the number pi?

It's the ratio between the circumference of any circle to its diameter.

### What is the difference between pi and the number three?

pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer. pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer. pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer. pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an…

### How can you calculate the exact value of pi?

22 divided by 7 * * * * * That is an APPROXIMATE value of pi. The exact value cannot be calculated since pi is a transcendental number - a special kind of irrational number. It has an infinite decimal representation with no recurring pattern. That would be true in any base - binary, octal, or another base (other than pi itself, or a power of pi).

### How can Pi find the volume of a sphere?

Volume = 4/3 * pi * radius3 'Pi' is just a number. It doesn't 'do' anything, any more than '6' does. The special thing about 'pi' is that it's the number that keeps popping up wherever circles are involved. So if a person is paying attention, it doesn't take him long to realize that he can use 'pi' to do things, like with angles, and with things that move in circles, and like finding the…

### What number divided by another number equals pi?

This has an infinite number of answers, for example: pi / 1, (2 x pi) / 2, 1 / (1/pi), etc. This has an infinite number of answers, for example: pi / 1, (2 x pi) / 2, 1 / (1/pi), etc. This has an infinite number of answers, for example: pi / 1, (2 x pi) / 2, 1 / (1/pi), etc. This has an infinite number of answers, for example: pi / 1…

### Why is pi special?

Because it's irrational. It goes on forever, the reason for this is that Pi is used to work out the circumference of a circle. Circles don't have sides, so you can't times one by another to get the Area. You have to use a number that goes on forever, because technically, a circle goes on forever. Mathematicians wanted a number to work out circles. And after much calculation, they finally discovered an irrational number, Pi…

### 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.

### 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…
