Earliest known usage of pi

pi

The earliest approximate value of π was first found in Egypt and Babylon, both covered within 1% of the genuine value.

In Babylon, a clay tablet dated 1900 - 1600 BC has a geometrical statement that, by implication, treats π as 25/8 = 3.1250.

In Egypt, the Rhind Papyrus, dated around 1650 BC, but copied from a document dated to 1850 BC has a formula for the area of a circle that treats π as (16/9)2 π 3.1605.

In India around 600 BC, the Shulba Sutras (Sanskrit texts that are rich in mathematical contents) treat π as (9785/5568)2 π 3.088.In 150 BC, or perhaps earlier, Indian sources treat π as sqrt(10) π 3.1622.
