How do you find the square feet of a circle if you have the radius?
Area of any circle = pi times radius squared.
What is the radius of a circle with an area of 32.1 square feet?
To find the radius of a circle given its area, you can use the formula for the area of a circle, A = πr². Rearranging this formula to solve for the radius gives r = √(A/π). Substituting the given area (32.1 square feet) into the formula, the radius is r ≈ √(32.1/π) ≈ 3.19 feet.
How many square feet in a 54 foot circle?
To find the area of a circle, you can use the formula A = πr², where r is the radius. For a 54-foot circle, the radius is 27 feet (half of the diameter). Therefore, the area is A = π(27)², which is approximately 2,295.6 square feet.
How many square feet in a 22 foot diameter circle?
To find the area of a circle, you use the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a diameter of 22 feet, the radius is 11 feet. Therefore, the area is ( A = \pi (11)^2 \approx 380.13 ) square feet.
How do you find the radius of an inscribed circle of a square given the area of the square?
Half the square root of the square radius equals the circle radius.
How do you convert square feet into a radius of a circle?

What is square footage of a 4 foot circle?
To find the square footage of a circle, you first need to calculate the area of the circle using the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, so the radius is 2 feet. Substituting the radius into the formula, we get A = π(2)^2 = 4π square feet. Therefore, the square footage of a 4-foot circle is approximately 12.57 square feet.
How do you find area of circle that is 4.3 ft?
Area in square feet = pi*radius squared
Square footage of a 24 foot circle?
To find the square footage of a 24-foot circle, first calculate the radius, which is half of the diameter: 12 feet. Then, use the formula for the area of a circle, A = πr². Substituting in the radius, the area is A = π(12)² = π(144) ≈ 452.39 square feet. Thus, the square footage of a 24-foot circle is approximately 452.39 square feet.
What is the square footage of a 24 foot diameter circle?
To find the square footage of a circle, you can use the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a 24-foot diameter, the radius is 12 feet. Plugging this into the formula gives ( A = \pi (12)^2 = 144\pi ) square feet, which is approximately 452.39 square feet.
What is the area of a circle if the diameter is 32 feet?
To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius. Since the diameter is 32 feet, the radius would be half of that, which is 16 feet. Plugging this into the formula, the area of the circle would be A = π(16)^2 = 256π square feet.
How many square feet in a 7.5 ft circle?
To find the area of a circle, you can use the formula ( A = \pi r^2 ). For a circle with a radius of 7.5 feet, the area would be ( A = \pi (7.5)^2 ), which is approximately ( 176.71 ) square feet. Therefore, a 7.5-foot circle has about 176.71 square feet of area.
