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.

Since it has long been accepted that the proof is in the pudding, not in the pi, perhaps the puzzle is not solvable.
