The Hindus created PI
The first person to use pi is the awesome man Archimedes he was the first to compute pi's value accurately! I know this answer and I'm in 5th grade!:)
the first person to use pi was the amazing thomas paul pearson
Egyptians and Mesopotamians and babylonians
first you do 23.5 X 23.5 (square it) which is 552.25. Then you multiply by pi. If your calculator has a pi button, use it, but if not, round to 3.14. 552.25 X 3.14 = 1734.065 If you have a pi button, you should get 1734.94454294496. Because Pi is irrational, even this is rounded. The easier way to use pi is 3.14 because you a most likely not expected to go out 20 decimal places for 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
people use pi to find the circumference of a circle.

people made fun of his name his real name is Piscine Molitor Patel. but instead the next year her decided to use the first 2 letters which is "Pi"
The first to find the value in pi were the Babylonians and Egyptians.
3.14159265 That Pi? Many people use Pi. I use Pi in my math class.
the ancient Egyptians used pi to build pyramids
the Babylonians were the first -haley
William Jones in 1706
pi=3.1415926535897932384626433.....but most of the time people just use 3.14

The ancient Babylonians used pi as a number approx 4000 years ago.
