Question

Find the volume of a sphere whose radius is $7$ cm.

Answer 1

Given, radius of the sphere $=7cm$

We know that the volume of sphere with radius $r$ is $V=\frac{4}{3}\pi r^3$.

Thus,

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

$=\frac{4}{3}\times \frac{22}{7}\times (7{)}^{3}c{m}^3$

$=\frac{4}{3}\times \frac{22}{7}\times 343c{m}^3$

$=1437.33c{m}^3$

Hence, the volume of the sphere is $1437.33c{m}^3$
