- Measure the diameter of your circle in feet.
- To calculate the area of a circle, we use the formula: π x (diameter / 2) 2. That is, (pi is 3.14159265) multiplied by half the diameter squared.
- This will give you your square feet (ft2).

### What is a circle radius?

The radius of a circle is the distance from the center of the circle to any point on its circumference. [1] The simplest way to find the radius is to divide the diameter in half.

### How do you find a diameter?

To find the diameter of a circle, multiply the radius by 2. If you don’t have a radius, divide the circumference of the circle by to get the diameter. If you don’t have a radius or perimeter, divide the area of the circle and find the square root of the number to get the radius.

### How is the area calculated?

To find the area of a rectangle, multiply the height by the width. For a square, all you have to do is find the length of one of its sides (since each side is the same length) and then multiply it by itself to find the area.
