Question

Find the volume of a sphere of diameter $6cm$.

Answer 1

Given: Diameter of sphere $=6cm.$

​Radius of the sphere, $r=\frac{6}{2}=3cm$​

​$\therefore$ Volume of the sphere, V $=\frac{4}{3}\pi r^3$

$=\frac{4}{3}\times 3.14\times 3^3=113.04c{m}^3$ [$\pi =3.14$]

Thus, the volume of sphere is $113.04c{m}^3.$
