He could measure
straight lengths. He found the value to be 3.1416 for the approximate
value of pi which multiplied by the radius would equal the perimeter of

He should have measured the diameter instead, which is easier than
measuring the radius (and would have given him the correct answer).

Just yanking your chain. Good discussion.
