The individual who can then be said as the one who discovered pi is Archimedes since he is the first one to compute the value of the pi quite accurately. The man who discovered pi did so by comparing the perimeters of two polygons inscribed in a single circle; one is outside the circle and the other inside. The ratio of the bigger polygon’s perimeter with the smaller one’s will then be equivalent to the one between a circle’s circumference and its diameter. Archimedes did this technique to a total of 96 polygons and he got the average ratio, which is 3.14185. The value may not be spot on and only correct up to two decimal places but it is an improvement nonetheless over the computed values that the civilizations before him came up with.
