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

Circumference of a circle is c=2πr
r=14in
-> c=2*14*π=28π

3 rotations->trace length=3c=3*28π=84*π inch≈263.89 inch≈22 feet
