The formula for the area of a circle, pi r^2, is traditionally attributed to ancient Greek mathematicians. The method for calculating the area of a circle was likely known in some form by earlier cultures, such as the Egyptians and Babylonians, but it was the Greeks who provided a more rigorous mathematical treatment. One of the key figures in this development was Archimedes of Syracuse (c. 287–212 BCE). Archimedes used a method involving the approximation of the circle by inscribed and circumsc
