# Right Circular Cylinder in Geometry

A right circular cylinder is a three-dimensional geometric shape composed of two circular bases connected by a curved surface. In geometry, a right cylinder is a cylinder in which the two bases are perpendicular to the cylinder's axis and the height of the cylinder is equal to the distance between the two bases. The radius of the circular bases is the same and the height of the cylinder is the same as the distance between the two bases.

## Formula for Calculating the Volume of a Right Circular Cylinder

The formula for calculating the volume of a right circular cylinder is V = pr^{2}h, where r is the radius of the circular base and h is the height of the cylinder.

For example, if the radius of the circular base is 4 cm and the height of the cylinder is 10 cm, then the volume of the right circular cylinder is V = p(4)^{2}(10) = 502.65 cm^{3}.

## Formula for Calculating the Surface Area of a Right Circular Cylinder

The formula for calculating the surface area of a right circular cylinder is SA = 2pr^{2} + 2prh, where r is the radius of the circular base and h is the height of the cylinder.

For example, if the radius of the circular base is 4 cm and the height of the cylinder is 10 cm, then the surface area of the right circular cylinder is SA = 2p(4)^{2} + 2p(4)(10) = 232 cm^{2}.

## Circumference of a Right Circular Cylinder

The circumference of a right circular cylinder is the perimeter of the two circular bases. The formula for calculating the circumference of a right circular cylinder is C = 2pr, where r is the radius of the circular base.

For example, if the radius of the circular base is 4 cm, then the circumference of the right circular cylinder is C = 2p(4) = 25.13 cm.
