__**WHO DISCOVERED PI, AND HOW DID THEY FIRST REALIZE IT?**__

Answer the question below, append new answers to the top of this page. _ __Response 1:__ Nilus Tong 8.4 Pi goes back a long time ago and is hard to find out who discovered pi. However the first person to actually find the value quite accurately would be Archimedes. He discovered it by comparing the perimeter of two polygons inscribed into a single circle. One on the outside of the circle and one on the inside. The ratio of the outer polygon perimeter should then be equivalent to the circumference and diameter of the circle. He did this 96 times with different sizes and found the average which was 3.14185. Archimedes number of pi that he found is different from the pi number we use today, 3.1416.
