r =
Radius of the cylinder, half the width across the widest part of the circular end
h =
Height of the cylinder, distance between the two round ends
A =
Area of the cylinder lateral surface area in square units
Choose the number of decimals to show in your answer. This is also known as significant figures. Select an appropriate amount of significant figures based on the precision of the input numbers.
Imagine a cylinder as a typical can, now unroll that can and discard the top and bottom, the remaining bit is the lateral surface area. As an unrolled piece we are given a rectange but as part of a cylinder we have the radius to work with. The length of the part before being unrolled is the circumference of the circular part of the cylinder, multiply that by the height and we have the surface area of the lateral part of a cylinder: A = 2π * r * h Given a cylinder we must know the radius and height to calculate the surface area of the lateral portion: You may also calculate the surface area of the entire cylinder with the same inputs by adding in the area of the end circles using the cylinder surface area calculator.Cylinder Lateral Surface Area Formula
