# The radius of a wheel of a bus is 0.70m . how many revolution will it make in covering 22km. (please use the formula of pi and please solve in proper way dont only give answer )

Radius of wheel, r = 0.70 m
circumference of the wheel = 2 $\mathrm{\pi }$ r = 4.4 m
no. of revolutions in covering 4.4 m = 1
no. of revolutions in covering 1 m = (1/4.4) m
no. of revolutions in covering 22000 m = (22000/4.4) = 220000/44 = 5000
