# The diameter of the base of a cylinder is 6 cm and its height is 14 cm.

Question:

The diameter of the base of a cylinder is 6 cm and its height is 14 cm. The volume of the cylinder is
(a) 198 cm3
(b) 396 cm3
(c) 495 cm3
(d) 297 cm3

Solution:

(b) $396 \mathrm{~cm}^{3}$

Volume of the cylinder $=\pi r^{2} h$

$=\frac{22}{7} \times 3^{2} \times 14$

$=22 \times 9 \times 2$

$=396 \mathrm{~cm}^{3}$
