Re: How many inches does my wheel go in one rotation?

Well it's quite simple actually.

So we have the well known mathematical fact that the number of inches that a wheel turns is proportional to the square of it's radius (denoted r). This factor is \pi.

If you have a wheel of diameter 2n, r = n.

We thus have:

turning distance = \pi * r^2.

It's quite simple really. I think this is covered in the first few weeks of AP CALCULUS BC.
