Question

If the diameter of the base of a cylinder is $14$ cm and its height is $12$ cm then the volume of the cylinder in $m^3$ is

• A. $10.1848$ $m^3$
• B. $0.001858$ $m^3$
• C. $0.001848$ $m^3$
• D. $18.48$ $m^3$

Answer 1

The correct option is D $18.48$ $m^3$

Diameter $=14$ cm

Height $=12$ cm

radius $\left(r\right)=\frac{14}{2}=7$ cm

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

$=\frac{22}{7}\times 7\times 7\times 12$

$=1848c{m}^2$

$=\frac{1848}{100}{m}^3$

$=18.48m^3$
