Area of a circle = pi*radius2
The area of a circle is pi*(radius)^2. If the 8 ft is the diameter, the area is pi*(4 ft)^2~=50.27 ft^2 (ft^2 is square feet)
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)
Assuming you mean 8' in diameter then area is pi x 16 or almost exactly 50¼ sq ft.
Using 3.14 as Pi the area of circle is: 0
Area = (pi) R2 R = 1/2 diameter = 4 ft 3 inches = 4.25 ft Area = (pi) (4.25)2 = 56.745 square ft (rounded)
Using 3.14 as Pi the area of circle is: 200.96
Using 3.14 as Pi the area of circle is: 200.96
c=pi*8 diameter = 8 radius = 4 area = pi * 16
Inner radius of walk = R1 = 10/2 ft = 5 ft. Outer radius of walk = R2 = 5ft + 3 ft = 8 ft Area of fountain = pi*R12 = 78.54 sq ft Area of fountain + walk = pi*R22 = 201.06 sq ft So area of path = 201.06 sq ft - 78.54 sq ft = 122.52 sq ft.
Area = pi * r * r = 3.14 * 8 * 8 = 3.14 * 64 = 200.96 square inches
area = pi*8 squared
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
