Question

A car tire has a radius of 10.4 inches. What distance will the tire travel after 20 rotations?

Answer 1

Distance traveled after 20 rotations = 1306.24 inches

Explanation:

r = 10.4 inches

Distance traveled in one rotation = Circumference of the car tire

Circumference of the car tire = 2πr

= 2 * 3.14 * 10.4

= 65.312 inches

Distance traveled after 20 rotations = 65.312 * 20

= 1306.24 inches
