Pi is the 16th letter of the Greek alphabet
several equations' answers come out to 3.14 and so on, thats pi
The Greek alphabet.
PI the 16th greek letter is the circumference divided by the diameter of a circle. For example 40.5/12.89 = PI.
Because pi = 0.5*tau
3.14 is short for pi. Pi can go on forever and ever. It's just a rounded number of pi to make things easier to understand.
Any circle's circumference divided by its diameter has a value of pi
The movie is already out.
who invented, or came up with "pi" in math? How did they come up with the estimation of 3.14?
Pi r squared comes from the formula to find the area of a circle.
The 16th letter of the Greek alphabet.
I have not yet come across a calculator with a single button for pi, but pi equals 22 divided by 7(3.142...). Hope I helped.

Archimedes was the first Western mathematician to make a serious attempt at calculating the value of pi. His estimated, that pi was between 3.1408 and 3.1429.
Probably re-arranged the alphabet and found it.
the great pyramids did this.
It's the value of pi rounded to 4 decimal places
pi is the ratio of a circle's circumference to diameter, and that number just happens to be, always, 3.14159.... for an infinite number of digits
The babylonians first discovered the ratio compared to the diameter and circumference of a circle. Later, Archimedes(287-212BC) discovered and proved his theory of pi. Pi to 27 decimal places: 3.141592653589793238462643383 The square root of pi (to 30 decimal places) is: 1.772453850905516027298167483314
um hi i think in 2013 march 18th
the same as pi squared, which is 9.86960440109
