Question

A bicycle wheel makes 10000 revolution in moving 22km find the diameter of the wheel

Answer 1

Distance travelled in 10,000 revolutions= 22km=22000m

Distance travelled in 1 revolution= 22000/10,000 m=2.2m

1 revolution=circumference

2.2m=2x22/7xr

2.2m=44/7xr

(2.2mx7)/44=r

0.35=r

Diameter= 2r= 0.70m
