Question

The diameter of a wheel of a car is 1.12 m. Find the distance covered by the car by completing one revolution.$(take\pi =\frac{22}{7})$

Answer 1

We know that, Radius of a circle $r=\frac{diameter}{2}=\frac{1.12}{2}=0.56m$

In one complete revolution, car covers a distance equal to perimeter of wheel $=2\pi r=2\times \frac{22}{7}\times 0.56=3.52m$
