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.

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

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 Babylonians were the first -haley
the ancient Egyptians used pi to build pyramids
William Jones in 1706
Archimedes first used the symbol PI because he was the first one to discover it so he wanted to investigate about it.
