How far does it go in 1revolution?  That would be the circumference.

anonymous · Answer

If I am correct, that would be 18pie.  I got that from calculated the circumference.  Do I need to multiply or divide that by the 900 revolutions.  If so, could you give me an explanation to why?  I won't remember otherwise.
