Surface area of a cylinder

Surface area of a cylinder

The surface area of a cylinder can be defined as the amount of space covered by a flat surface of the base of the cylinder and the curved surface of the cylinder. The surface area of the cylinder is actually the sum of an area of a circle since the base of the cylinder is a circle and the area of curved surface which is a rectangle of length height of the cylinder and circumference of the base as width. Surface area is expressed as the "number of" square units (square centimeters, square inches, square feet, etc.).

Cylinder

The formula of the surface area of the cylinder is used to find the surface area occupied by the bases of the cylinder within its boundary and the curved surface of the cylinder. As a cylinder has a curved surface, thus we can express its curved surface area as well as total surface area. A cylinder has two kinds of surface area: The area of any shape is the space occupied by it. A cylinder has 2 flat surfaces which are usually circles and a curved surface that opens up as a rectangle. Consider the cylinder whose height is 'h' and a circular base with radius, 'r'. Let us open a cylinder and see this.

The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder = 2πr(h + r), while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where 'r' is the radius of the base and 'h' is the height of the cylinder. Surface area of cylinder can be easily evaluated or determine using the surface area of cylinder calculator. It is the fastest method with which we can evaluate the surface area within few seconds. To use the same we need to input the value of the specific parameters in the calculator screen such as a radius, height of the cylinder.
