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
PI the 16th greek letter is the circumference divided by the diameter of a circle. For example 40.5/12.89 = PI.
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.

Pi is the 16th letter of the Greek alphabet
several equations' answers come out to 3.14 and so on, thats pi
Because pi = 0.5*tau

Pi r squared comes from the formula to find the area of a circle.
who invented, or came up with "pi" in math? How did they come up with the estimation of 3.14?
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.
