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 

To calculate the base area, multiply pi by the diameter squared divided by 4.

How to Calculate Base Area?

The following example problems outline how to calculate Base Area.

Example Problem #1:

  1. First, determine the diameter of the cylinder.
    • The diameter of the cylinder is given as: 4.
  2. 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 = ?
