Question

The diameter of a wheel is $70$ cm. Find the distance covered by wheel in $5$ revolution.

Answer 1

Distance covered will be$=$Number of revolutions $\times$ Circumference

Radius of wheel $=\frac{70}{2}=35$ cm

Distance covered in $5$ revolutions will be

$D=5\times 2\pi \times 35=5\times 2\times 35\times \frac{22}{7}=1100cm=11m$
