### What is Cylinder?

A cylinder is a three-dimensional shape with two round shapes at either end and two parallel lines connecting the round ends. Bases are always parallel and congruent to each other. Here, you will learn the Definition of Cylinder | Type of Cylinder | Properties of Cylinder | Formula.

### Type of Cylinder:

There is two type of cylinder:
1. Right Circular Cylinder
2. Oblique Cylinder

### Oblique Cylinder

When one of the bases of the cylinder is sideways and the axis is not a right angle to the base, then it is an oblique cylinder.

### Right Circular Cylinder

When the two bases of the cylinder are over each other in the exact position and the axis is at the right angle to the base, it is called cylinder is a right cylinder.

If the bases are circular in shape, then it is called a Right circular cylinder.
If the bases are in an elliptical shape, then it is called an Elliptical Cylinder.

If r, h is denoted radius, height of right Circular Cone then:

### Volume of Cylinder

Volume of Cylinder is defined as the total space occupied by the cylinder. The volume is denoted as “V”. It is measured in terms of cubic units.

Volume = πr2h

### Curved Surface Area of Cylinder

Curved Surface Area is the area of all the curved regions

Curved surface Area= 2πrh

### Total surface Area of Cylinder

Total Surface Area is the area of all the surfaces including the base of a 3D object

Total surface Area= 2πr( r + h )

### Properties of Cylinder

• A cylinder has only one curved side.
• A cylinder has two identical flat ends that are circular or elliptical.
• The bases are always congruent and parallel.
• It is similar to the prism since it has the same cross-section everywhere.
