If $\pi=\frac{22}{7}$, then find the distance covered in the revolution $( in\ m)$ of a wheel of diameter $35\ cm$.

Given: Diameter of a wheel is $35\ cm$.

To do: To find the distance covered in a revolution of a wheel.

Solution:

As given, diameter of a wheel$=35\ cm$

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

Therefore, circumference of the wheel $=2\pi r$

$=2\times \frac{22}{7}\times\frac{35}{2}$

$=110\ cm$

Thus, distance covered in a revolution by the wheel is $110\ cm$.
