# The largest sphere is to be curved out of a right

Question:

The largest sphere is to be curved out of a right circular cylinder of radius 7 cm and height 14 cm. Find the volume of the sphere.

Solution:

$=\frac{h}{2}$

$=\frac{14}{2}$

$=7 \mathrm{~cm}$

Volume of sphere

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

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

$=1437.3 \mathrm{~cm}^{3}$
