An oblique cylinder with a base of radius 2 units is shown. The top

Anuta_ua [19.1K]

The volume of the cylinder is the amount of space on it

The volume of the oblique cylinder is 174.19 cubic units

<h3>How to determine the volume of the cylinder?</h3>

The given parameters are:

AB = 16 units

Radius (r) = 2 units

$\theta = 30^o$

Start by calculating the height (h) using:

$h = 16 * \cos(30^o)$

This gives

$h = 13.86$

The volume of the cylinder is then calculated as:

$V = \pi r^2 h$

This gives

$V = 3.142 * 2^2 * 13.86$

$V = 174.19248$

Approximate

$V = 174.19$

Hence, the volume of the oblique cylinder is 174.19 cubic units
