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.
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
Area of a circle = (1/4) x (pi) x (square of the diameter)
Area = (1/4)*Ï€*d2 where d is the diameter. So area = pi*121/4 = 95.033 sq ft (to 3 dp)
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)
(1248/pi) ft ^ (1/2) = 19.9 ft
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 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.
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
Area = 1/4*Pi*d2 = 0.25*3.14*625 = about 490.63ft2
Area = 1/4*Pi*d2 = 0.25*3.14*162(256)= about 200.963ft2
Area of a circle = (1/4) x (pi) x (square of the diameter)
Area = (1/4)*Ï€*d2 where d is the diameter. So area = pi*121/4 = 95.033 sq ft (to 3 dp)
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'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)
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
Area = (pi) R2 R = 1/2 diameter = 4 ft 3 inches = 4.25 ft Area = (pi) (4.25)2 = 56.745 square ft (rounded)
