Omar races his bicycle for 152m. A wheel of his bicycle turns 38times as the bicycle travels this distance. What is the diameter of the wheel?

physics 
drwls,
N*pi*D = 152 m
N is the number of turns (38)
Solve for D
D = 1.27 meters
Most bicycles have diameters less than this.. more like 0.68 meters
