Archimedes was a brilliant Greek Mathematician living around 250 BC. He got a value for Pi whose accuracy would not be passed for another 400 years. The way he did it was to calculate the perimeter of a hexagon inside a circle, and one outside a circle. He then developed a formula to calculate the perimeter of a shape with twice as many sides, so 6 became 12 sides, became 24, 48, and finally 96 sides.
