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?

3 answers

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
Basically... yeah.
To be more consise...

Number of turns = N
Pi = Pi

N times Pi = Diamater

Thats how you do it ;)
