Step-by-step explanation:
We know, the circumference of the circle with radius r is given as Circumference=2πr .
So, distance travelled the wheel in one rotation =2πr
=2×22/7×0.7=4.4m.
In one rotation, the wheel covers 4.4 m.
Let us assume that in x
rotations, the wheel covers 1.1 km = 1100m.
x*4.4=1.1km*1000
x=250 rotation.
