Find the volume of a sphere whose radius is $3.5\ cm$.

 Given:

The radius of a sphere is $3.5\ cm$.

To do:

We have to find the volume of the sphere.

Solution:

Radius of the sphere $(r)=3.5 \mathrm{~cm}$

$=\frac{7}{2} \mathrm{~cm}$

Therefore,

Volume of the sphere $=\frac{4}{3} \pi r^{3}$

$=\frac{4}{3} \times \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \times \frac{7}{2}$

$=\frac{539}{3}$

$=179.67 \mathrm{~cm}^{3}$
