Pi is a number that is never ending, but most people only use the first couple of digits. pi = 3.14159265 pi is the ratio of a circles' diameter to its circumference

there are 10 trillion decimals for pi (or even more) but most people use 3.14 or 3.1415 and personally i use 3.141592654 answer by Jopiesaus

the number is that you use for pi is 3.14 the number is that you use for pi is 3.14

Pi is the number you have to use to solve many circle equations. If you want to find the area of a circle, use radius squared times pi. For the circumference, use diameter times pi.

The answer is 427.04 if we use 3.14 as pi.

By definition, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it. For the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it. Here's pi to many more digits: 3.14159265358979323846. The area of a circle is pi times the square of the length of the radius, or "pi r squared": A = pi*r^2
