Enter the value of a from the polar equation into the Cardioid Area Calculator. The calculator will evaluate the Cardioid Area.

## Cardioid Area Formula

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

CRA = 6*pi*a^2

- Where CRA is the Cardioid Area
- a is the value of
**a**from the polar equation

To calculate a cardioid area, multiply the a value squared by 6 times pi.

## How to Calculate Cardioid Area?

The following example problems outline how to calculate Cardioid Area.

Example Problem #1:

- First, determine the value of a from the polar equation.
- The value of a from the polar equation is given as: 3.

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

CRA = 6*pi*a^2

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

CRA = 6*pi*3^2 = 169.6

Example Problem #2:** **

For this problem, the variables required are provided below:

value of a from the polar equation = 6
