Question

The circumference of the base of a cylinder is 88 cm and its height is 60 cm. Find the volume of the cylinder and its curved surface area.

Answer 1

Circumference of the base of cylinder =88 cm.

$\because$ radius $=\frac{circumference}{2\pi }=\frac{88\times 7}{2\times 22}=14cm$

Height (h)=60 cm.

$\therefore$ Volume $=\pi r^{2}h=\frac{22}{7}\times 14\times 14\times 60c{m}^3$

$=36960c{m}^3$ and curved surface area $=2\pi rh$

$=88\times 60=5280c{m}^2$
