## Cylinder

An oblique cylinder is a cylinder, where the two circular end planes are parallel to each other, but unlike the right circular cylinder the lateral surface (the curved surface) is not perpendicular to the end planes.

## Area and volume of an oblique cylinder

**Area and volume of an oblique cylinder**

The volume of an oblique cylinder can be calculated in two ways.

If the length (a) of the lateral surface is given:

If the cylinder’s height (h) is given:**The area of the lateral surface of an oblique cylinder**

If the length (a) of the lateral surface is given:

If the cylinder’s height (h) is given:**Area of the entire surface of an oblique cylinder**

First you calculate the area of the lateral surface with the formula above, and then you add the area of the two circular end planes calculated with the formula:
