Question

Calculate the volume of the following cylinder.

Base radius $=5cm$; Length $=8cm$
$(\pi =3.142)$

• A. $628.4c{m}^3$
• B. $728.4c{m}^3$
• C. $828.4c{m}^3$
• D. None of these

Answer 1

The correct option is A $628.4c{m}^3$

The volume of a cylinder of radius $r$ and height $h$ is given by $\pi r^{2}h.$

Given:

$r=5cm$

$h=8cm$

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

$=3.142\times 5\times 5\times 8$

$=3.142\times 200$

$=628.4c{m}^2$
