heya frnd!
here's ur answer...
given the diameter of the wheel is 70km.
therefore it's radius will be=70/2
=35cm
circumference of the wheel=2πr
=2×22/7×35
=44×5
=220cm
we know that 1km=100000cm
therefore 4.4km=440000cm
no. of revolutions it will take to cover that distance=440000/220
=2000
hence it will take 2000revolution to cover 4.4km
hope this helps..!
