The expression 2πrh represents the surface area of the cylinder.
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Let r be the radius and h be the height of the cylinder.
Then the surface area of the cylinder will be
Surface area = Base area of cylinder x Height of cylinder
Given a right cylinder where h is the height, and r is the radius.
The surface area is the product of base area of cylinder and height of cylinder.
Then the surface area of the cylinder will be given as,
Surface area = 2πrh
Thus, the expression 2πrh represents the surface area of the cylinder.
The diagram of the right circular cylinder is given below.
