A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 14 inches,and the bicycle wheel mkes 3 full rotations before stopping. How long is the trace of water on the floor?

Answer 1

radius = 14 inches
one round of the tire =
`2 \pi r`
one round of the tire =
`2 \pi (14)`
one round of the tire = 87.96 inches
three rounds of the tire = 87.96 x 3 = 263.89 inches
