Re: How many inches does my wheel go in one rotation?
Which brings up this old joke. A hillbilly finally sent his son into town to go to school, rather than relying on the old McGuffie Reader at home. In math they were studying geometry, the area of circles. But the boy didn't understand something. The teacher kept saying, "Pi R squared." The boy said, "Pie are round. Cornbread are square."
