Question

.The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel?

Answer 1

1271.7in

Explanation:

A complete rotation is = circumference of the wheel.

So calculate the circumference which is pi times diameter.

27 times pi (which is 3.14) = 84.78in one rotation

so if you make 15 rotations, you are multiplying it by 15

15 x 84.78 = 1271.7in
