# Proof of Pi

Assume we know nothing of Pi's actual value. Apparently, we think it is some random number generated by a calculator every time the Pi button is pressed. All we know that is 2*Radius*Pi is the circumference of a circle and pi*radius*radius is area. Use a unit circle to prove that Pi is >3 and <4.
