Question

A bicycle tire has a radius of 14 inches. How far will the bicycle travel in 40 rotations of the tire?

When calculating circumference you are calculating one rotation. What do you
need to do to get 40 rotations?

Answer 1

Explanation:

Multiply by 40 :) the answer for the part in red

Pi r = circumference , or all the way around the tire on the outside , once

pi * 14

43.98229 inches = circumference

40 * 43.98229 = 1759.291 inches

1759.291 / 12 = 146.6 feet
