4. Thewheel of a bullock cart has a diameter of 1.4m. How many rotations will thewheel complete as the cart travels 1.1km?

Answer»

In one rotation distance covered= 2*pi*r= 2*22/7*.7= 44/10 = 22/5

Let wheel complete n rotations in 1.1 kmThenn*22/5 = 1.1*1000n = 1100*5/22 = 500/2n = 250

Thus bullock cart complete 250 rotations
