Enter the diameter of the cylinder into the Base Area Calculator. The calculator will evaluate the Base Area.

## Base Area Formula

The following two example problems outline the steps and information needed to calculate the Base Area.

**BA = pi*(D/2)^2**

- Where BA is the Base Area
- D is the diameter of the cylinder

## How to Calculate Base Area?

The following example problems outline how to calculate Base Area.

Example Problem #1:

- First, determine the diameter of the cylinder.
- The diameter of the cylinder is given as: 4.

- Finally, calculate the Base Area using the equation above:

BA = pi*(D/2)^2

The values provided above are inserted into the equation below and computed.

BA = pi*(4/2)^2 = 12.566

Example Problem #2:** **

For this problem, the variables required are provided below:

diameter of the cylinder = 6

Test your knowledge using the equation and check your answer with the calculator..

BA = pi*(D/2)^2** = ?**
