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 × 2.8
Distance = 44/7 × 2.8
Distance = 17.6
____________________________
THEREFORE,
22 km = 22000 m
No. of Revolutions made =
=>Total Distance / Distance covered in 1 revolution
No. of revolutions = 22000 / 17.6
No. of revolutions = 1250
_____________________________
ANSWER =
No. of revolutions = 1250
