## Formula to Find Area of a Circle in Excel

Method Formula
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:

### 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)
