Find the volume of a sphere whose diameter is $14\ cm$.

 Given:

The diameter of a sphere is $14\ cm$.

To do:

We have to find the volume of the sphere.

Solution:

Diameter of the sphere $= 14\ cm$
This implies,

Radius of the sphere $(r)=\frac{14}{2}$

$=7 \mathrm{~cm}$

Therefore,

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

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

$=\frac{4312}{3}$

$=1437.33 \mathrm{~cm}^{3}$
