if a bike tire is measured to be 2 feet across. how far will the bike travel for every turn of the tire?

Question

what is the estimate, is it reasonable.... why or why not?

 

Answer 1

C=Π*d, with d=2.

You can estimate by using 3 for pi, so each turn will be approximately 2*3 feet. The more the wheel turns, the less accurate the estimate will become.
