Area of a circle is defined as
A = pi x radius2
So if the diameter is 1 ft, the radius is 1/2 ft. I'll use pi=3.14. So the problem in feet is:
pi x (1/2)2 = 3.14 x 1/4 = .785 sq ft
In inches, radius = 6 inches so:
pi x 62 = 3.14 x 36 = 113.04 sq in

The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
How many square feet is 24 inch circle?
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
What is the area of a circle with a diameter of 11 feet?
Area = (1/4)*Ï€*d2 where d is the diameter. So area = pi*121/4 = 95.033 sq ft (to 3 dp)
Area of circle with diameter?
Area of a circle = (1/4) x (pi) x (square of the diameter)
What is the square footage of a 60 foot circle?
What's a "60 foot circle" ? Does that mean the diameter is 60-ft ?Area of a circle = (pi) (radius)2 .Radius = 1/2 diameterIf the diameter is 60-ft, then area = (pi) (30)2 = (900 pi) = 2,827.43 square feet (rounded)
If the area of a circle is 312 sq ft what is the diameter?
(1248/pi) ft ^ (1/2) = 19.9 ft
How much water would fill up a cylinder with diameter 2 ft and 1 ft tall?
Volume of a cylinder is: Area of the circle x depth Area of a circle is: (pi * diameter^2)/4 where diameter is 2 ft Depth is: 1 ft Therefore, the volume of the cylinder is 3.14ft^2 * 1 ft = 3.14 cubic feet of water
The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
How many square feet is 24 inch circle?
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
What is the area of a circle with diameter 25 ft?
Area = 1/4*Pi*d2 = 0.25*3.14*625 = about 490.63ft2
Area of a circle with a 16 ft diameter?
Area = 1/4*Pi*d2 = 0.25*3.14*162(256)= about 200.963ft2
What is the area of a circle with a diameter of 11 feet?
Area = (1/4)*Ï€*d2 where d is the diameter. So area = pi*121/4 = 95.033 sq ft (to 3 dp)
Area of circle with diameter?
Area of a circle = (1/4) x (pi) x (square of the diameter)
What is the area of a circle with a radius of 16ft?
Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16-ft, radius = 8-ft, and area = (pi) (8)2 = 201.062 square feet (rounded)
What is the square footage of a 60 foot circle?
What's a "60 foot circle" ? Does that mean the diameter is 60-ft ?Area of a circle = (pi) (radius)2 .Radius = 1/2 diameterIf the diameter is 60-ft, then area = (pi) (30)2 = (900 pi) = 2,827.43 square feet (rounded)
Which area is bigger a circle with a diameter of 10 feet or a triangle with an area of 100 sq ft?
Use the standard formula to calculate the area of the circle, then you can compare with the area given for the triangle. Note 1: The formula for a circle is: area = pi x radius squared Note 2: The radius is half the diameter
How many square feet in a circle that is 8 feet 6inches in diameter?
Area = (pi) R2 R = 1/2 diameter = 4 ft 3 inches = 4.25 ft Area = (pi) (4.25)2 = 56.745 square ft (rounded)
