Question

The diameter of the wheel of a cart is 1.05 m. How much distance will the cart cover in 1000 rotations of the wheel?

Answer 1

Diameter = 1.05 m
Circumference of the wheel = $2\mathrm{\pi }r$
= $2\times \frac{22}{7}\times \left(\frac{1.05}{2}\right)=3.3$m
In 1000 rotations, the distance covered = 3.3 m × 1000 = 3300 m = 3.3 km
