## About Surface Area of a Cylinder Calculator (High Precision)

The Surface Area of a Cylinder Calculator is used to help you find the surface area of a cylinder (Step by Step).

## 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 = 2πr^{2}

2. Surface area of the side

A = 2πrh

3. Total surface area of a cylinder

A = 2πr^{2} + 2πrh = 2πr(r + h)

Where:

A = surface area of a cylinder

π = 3.141592654

r = radius

h = height
