- 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).

The formula for the circumference of a circle is C = 2∏r, where r = radius. To find the radius we add 18 for the perimeter. So 18 = 2∏r. The solution for r is 9 / or about 2.86 inches.
To calculate the circumference of a circle, use the formula C = πd, where C is the circumference, d is the diameter and 3.14. If you have a radius instead of a diameter, multiply it by 2 to get the diameter. You can also use the formula for the perimeter of a circle with a radius that is C = 2πr.
The circumference of an 8-inch diameter circle is 25.12 inches.
Circumference = 62,857 feet. Answer: The circumference of the circle, which is 20 feet in diameter, is 62,857 feet.
The radius of a circle is the distance from the center of the circle to any point on its circumference.  The simplest way to find the radius is to divide the diameter in half.
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.
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.

Area of a circle of 50 feet 7,854.0 square feet 1,130,973 square feet 729.66 square feet 7,296,588 square inches
To calculate the area of a room in square feet, measure the length and width of the room in feet and multiply those numbers to get an area in square feet. For example, a 12 x 15 foot room with an area of 180 ft² (12 x 15 = 180) is described.
Area of a 20-foot circle 1,256.6 square feet 180,956 square meters 116.75 square meters 1,167,454 square centimeters
Cubic feet = square feet × depth. So: 20 × 0.25 = 5. We have a total of: 5 cubic feet.
