Question

A bicycle tire has a diameter of 38 inches. Which is the distance the tire will travel in one complete revolution?

Answer 1

119.4 in.

You need to find the circumference (2πr) of the tire to find the answer.

Remember to find the radius (d/2) first, because the question is trying to trick you by telling you the diameter of the tire.

Answer 2

C=πd

C=3.14 x 38

C=119.32

Therefore, the distance would be 119.32 inches.
