Who used math to create pi?

Pi, the mathematical constant representing the ratio of a circle's circumference to its diameter, has been studied by various cultures throughout history. Ancient civilizations, including the Babylonians and Egyptians, approximated pi using geometric methods. The symbol "π" was first introduced by the Welsh mathematician William Jones in 1706, and it was popularized by the Swiss mathematician Leonhard Euler in the 18th century. Thus, while no single person "created" pi, its study and understanding have evolved through contributions from many mathematicians over time.
