About Surface Area of a Cylinder Calculator

The online Surface Area of a Cylinder Calculator is used to help you find the surface area of a cylinder.

Surface Area of a Cylinder Formula

The following is the calculation formula for surface area of a cylinder.

1. Surface area of the top and bottom

A = 2πr2

2. Surface area of the side

A = 2πrh

3. Total surface area of a cylinder

A = 2πr2 + 2πrh = 2πr(r + h)

Where:
A = surface area of a cylinder
π = 3.141592654
r = radius
h = height
