Question

Find the volume of sphere whose radius is $3$ cm.

Answer 1

As we know that volume of sphere of radius '$r$' is given as-

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

$\because r=3;cm\left(\text{Given}\right)$

$\therefore V=\frac{4}{3}\times \frac{22}{7}\times {\left(3\right)}^3=113.143{cm}^3$

Hence the volume of sphere of readius $3cm$ is $113.143{cm}^3$.
