The radius of a wheel of a bus is 0.70 M How many revolution will it make in covering 22 KM?​

Answer 1

Answer:

Radius = 0.70 m

In one revolution, the wheel will roll once around its circumference, so one revolution equates to a distance of :

Circumference = 2 π r

Distance/Circumference = 2 π r

Distance = 2 × 22/7 × 0.7

Distance = 44/7 × 0.7

Distance = 44/10 m

Distance = 4.4 m

____________________________

THEREFORE,

22 km = 22000 m

No. of Revolutions made =

=>Total Distance / Distance covered in 1 revolution

No. of revolutions = 22000 / 4.4

No. of revolutions = 5000
