What is Pi?
Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter.
It is an infinitely long, irrational number, and its exact value cannot be known. Pi is roughly equal to 3.14 or 22/7.
The value of Pi was first calculated by a mathematician named Archimedes of Syracuse. It was later accepted by the scientific community when Leonhard Euler used the symbol of Pi in 1737.
