Radius of a wheel = 0.7 m
Total distance to be travelled= 22 km
=22 × 10^3 m
circumference of a wheel= 2× pie × r
=2 × 3.14 × 0.7
=4.396
Now,
total no. of revolutions=total dist.
to be travelled/circumference
= 22000/4.396
= 5004.5 revolutions
OR
lets take pie as 22/7
circumference =0.7× 22/7×2=0.2×22=4.4
no of revolution, =22000/0.2×22=1000/0.2
=5000 revolutions
