## Formula to Find Area of a Circle in Excel

Method | Formula |
---|---|

Using Radius | =PI() * (radius)^2 |

Using Diameter | =PI() * (diameter/2)^2 |

Using Circumference | =circumference^2 / (4 * PI()) |

Calculating the area of a circle can be done using different methods in Excel, depending on the information you have available. Let’s explore these methods:

### 1. Area of a Circle Using Radius

To calculate the area of a circle when you have the radius, you can use the formula:

Area = π * (radius)^2

### 2. Area of a Circle Using Diameter

If you have the diameter of the circle, you can calculate the area using:

Area = π * (diameter/2)^2

### 3. Area of a Circle Using Circumference

If you know the circumference of the circle, you can find the area with:

Area = (circumference^2) / (4 * π)

## Key Takeaways

- The area of a circle can be calculated using various methods in Excel: radius, diameter, or circumference.
