How many times a wheel of a radius 28 cm must rotate to go 352m

Answered by admin @ 11/08/2021

Given radius =28 cm
area of the wheel(as it is a circle)=2πr
=2×(22÷7)×28=176cm
as it must rotate 352m which is given meter's we need to convert it in cm
35200

hence no of time it rotates=35200÷176=200times
