Since Pi's exact value cannot be known, we can never find the exact area or circumference of a circle.

Interestingly, legendary mathematician Albert Einstein's birth anniversary falls on Pi day.

Pi is a part of Egyptian mythology. It is being said that the Pyramids of Giza are built with the principles of Pi.

The value of the Pi was first calculated by Archimedes.
