Find the volume of a sphere whose radius is 0.63 m.

Given:

Radius of the sphere $=0.63\ m$.
To do:

We have to find the volume of the sphere.

Solution:

We know that volume of a sphere of radius 'r' is $\frac{4}{3} \pi r^3$.
Therefore,

Volume of the given sphere$=\frac{4}{3} \pi (0.63)^3$

$=\frac{4}{3}\times\frac{22}{7}\times0.63\times0.63\times0.63\ m^3$

$=4\times22\times0.09\times0.21\times0.63\ m^3$

$=1.05\ m^3$

The volume of the sphere is $1.05\ m^3$.
