According to Exploratorium.edu:

“Mathematicians began using the Greek letter π in the 1700s.

Introduced by William Jones in 1706, use of the symbol was popularized by Leonhard Euler, who adopted it in 1737.

An eighteenth-century French mathematician named Georges Buffon devised a way to calculate π based on probability.”
