The area would be found by taking the square of 2.5 feet, and then multiplying that square by the value of pi, approximately 3.14. So the product = 2.5 ft X 2.5 ft X 3.14 will give you the area of a circle that has a diameter of 5 feet.
This comes from the formula for the area of a circle:
A = pi X r2

How many square feet in a 1 foot diameter circle?
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
What is the area of a circle with a 5 inch diameter?
The area of a circle with a 5-inch diameter is: 19.63 square inches.
What is the area of a semi-circle with a diameter of 5?
The area of a semi-circle with a diameter of five is: 9.817 units2
How many square feet in a 10 foot diameter circle?
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is 10 feet, the radius would be half of that, which is 5 feet. Plugging this into the formula, we get A = π(5)^2 = 25π square feet. This is approximately 78.54 square feet.
How many square inches in a 5 foot diameter circle?
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
