The earliest known textually evidenced approximations of pi date from around 1900 BCE; they are 25/8 (Babylonia) and 256/81 (Egypt), both within 1% of the true value.
The Greek letter pi was first used to represent the ratio of the circumference of a circle to its diameter in 1709 by mathematician William Jones.
