A bicycle tire has a stone stuck in it. The radius of the tire is 46cm. Every time the wheel turns, the stone hits the ground.
a.) How far will the bicycle travel between the stone hitting the ground the first and second time?
b.) How many times will the stone hit the ground when the bicycle travels 1km?
C = 2πr = 2(3.14)46 = ?
! km = 1000m = 100,000cm
100,000/C = ?
