Question

Shirley wants to find the distance her unicycle moves on the sidewalk when the tire makes one complete revolution. If the diameter of her unicycle tire is 14 inches, find the distance the unicycle moves in one complete revolution. Use as an approximation for pi.

Answer 1

44 in

Explanation:

The circumference of the tire will be the same as the distance the unicycle moves in one complete revolution.

Find the circumference with the formula C =
`\pi`d, where d is the diameter

Plug in the values:

C =
`\pi`(14)

C = approx. 44 in
