Question

The wheels on A bike have a radius of 8.5 inches. If the wheels make 15 complete rotations, how far does the bike travel?

Answer 1

Hello!

`\large\boxed{\text{D = 255pi in or 800.7 in}}`

Solve for the distance by solving for the circumference of the wheels:

C = 2rπ

C = 2(8.5)(π)

C = 17π

The wheels make 15 rotations, so multiply the circumference by 15:

17π × 15 = 255π or ≈ 800.7 inches
