How man square feet in a 21ft diameter circle?
The area of a circle can be calculated using the formula: A = πr^2. If the diameter is 21ft, the radius would be half of that, which is 10.5ft. The area of the circle would be approximately 346 square feet.
What is the area The diameter of a circle is 8 feet.?
The area of a circle can be found using the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 8 feet, the radius would be half of the diameter, which is 4 feet. Plugging this into the formula, the area of the circle is approximately 50.27 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 circle that is 15 feet in diameter?
Area of a circle is PI times the square of the radius (half the diameter). 3.1415 x (7.5 squared) = about 176.7 square feet
What is the area of a circle with a diameter of 27 feet?
The Area of a circle = pi x r x r where pi = 3.14 and r is half the diameter or 13.5 feet A = 3.14 X 13.5 X 13.5 = 572.3 sq. feet
How man square feet in a 21ft diameter circle?
The area of a circle can be calculated using the formula: A = πr^2. If the diameter is 21ft, the radius would be half of that, which is 10.5ft. The area of the circle would be approximately 346 square feet.
What is the area of a circle with a diameter of 26 feet?
Well, darling, to find the area of a circle, you use the formula A = πr^2. Since the diameter is 26 feet, the radius is half of that, which is 13 feet. Plug that into the formula, and you get an area of approximately 530.66 square feet. Voila!
What is the area The diameter of a circle is 8 feet.?
The area of a circle can be found using the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 8 feet, the radius would be half of the diameter, which is 4 feet. Plugging this into the formula, the area of the circle is approximately 50.27 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.
Will something with the diameter of 25 feet fit into a circle with an area of 11.5 feet?
No, area of a circle is pi x radius x radius Radius is half the diameter. So the diameter of something giving 11.5 square feet as an area, must be much much smaller.
How many square feet in a circle that is 15 feet in diameter?
Area of a circle is PI times the square of the radius (half the diameter). 3.1415 x (7.5 squared) = about 176.7 square feet
What is the area of a circle with a diameter of 27 feet?
The Area of a circle = pi x r x r where pi = 3.14 and r is half the diameter or 13.5 feet A = 3.14 X 13.5 X 13.5 = 572.3 sq. feet
The Diameter of the circle was 4 feet what is the area?
First find out the radius (it is simply half the diameter). Then use the formula area = pi x radius2.
What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
If the diameter of a circle is 8 feet what is its radius?
4 feet. The radius is half the diameter.
What is the area in square feet of a 70 foot circle?
The area of any circle is determined by the formula: A = πr2 where A is the area, π is "pi", the ratio of a circle's circumference to its diameter (approximately 3.1416), and r is the radius of a circle, or half its diameter. If your diameter is 70 feet, the radius is 35 feet. So, ... A = πr2 = (app) 3.1416 x 352 = (app) 3,848 square feet, or about 0.09 acres.
What is the formula for the area of a circle with a diameter?
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
