Question

PLS HELP! A bicycle tire has a radius of 13.5 inches. How far will the bicycle travel in 100 rotations of the tiree?

Answer 1

8478

Explanation:

13.5x2xπ=84.78

84.78x100=8478

Answer 2

8482.3 inches

Explanation:

You have to find the circumference of the wheel.

If the radius is 13.5, the diameter is 27 (13.5 x 2).

C = πd

C = π × 27

C = 27π

100 rotations means 27π × 100 = 2700π

= 8482.3 inches
