What is Cylinder?

A cylinder is a three-dimensional shape with two parallel circular bases that are connected by a curved lateral surface. It is a type of geometric solid that can be described by three main dimensions: the radius of the base, the height of the cylinder, and the diameter of the base.

The volume of a cylinder is given by the formula:

V = πr^2h

Where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.

For example, if the radius of the base of the cylinder is 5 cm and the height of the cylinder is 10 cm, the volume would be:

V = π(5 cm)^2(10 cm) = 250π cm^3 ≈ 785.4 cm^3

Note that the volume is given in cubic units, so in this example, the volume is 785.4 cubic centimeters.

Cylinders are common shapes in everyday life, such as soda cans, drinking glasses, and paper towel rolls. They are also used in engineering and construction, for example, in the design of pipes and structural columns.

The surface area of a cylinder can be calculated using the formula:

A = 2πr^2 + 2πrh

Where A is the surface area, r is the radius of the base of the cylinder, and h is the height of the cylinder.

The lateral surface area of a cylinder is the area of the curved lateral surface and can be calculated using the formula:

A = 2πrh

Where A is the lateral surface area, r is the radius of the base of the cylinder, and h is the height of the cylinder.
