Nobody ever has because the true value of pi has never been worked out and we only use an approximation of pi when calculating the area of a circle.
actually no one knows..
Archimedes discovered how to work out the area of the circle, and he also discovered pi.

No, Pi was discovered, not created. Albert Einstein started the idea of Pi, where you multiply 3.14 with the diameter of a circle to get the circle's circumference, and where you multiply 3.14 squared with a circle's radius to get the circle's area, etc.
