The surface area of a sphere with a 24 inch diameter is 1809.6 square inches = 12.6 sq feet
A 56-inch diameter circle has an area of about 17.06 square feet.
A 72-inch diameter circle has an area of: 28.3 square feet.
A 48-inch diameter circle has an area of: 12.57 square feet.
A circle with a diameter of 300 inches has an area of 490.87 square feet.
Square footage (surface area) of a 36 inch diameter sphere = 4pir2 pi = 3.1416 r = 1/2 X diameter You asked for square footage; so first convert 36 inches to feet 36 inches / 12 inches/foot = 3 feet r = 1/2 X 3 feet = 1.5 feet surface area = 4 X 3.1416 X (1.5 feet)2 = 28 square feet

A 20-inch diameter circle contains: 314.16 square inches.
A 36-inch diameter circle has an area of: 1,017.9 square inches.* * * * *which is 7.07 square feet.
The surface area of a 12-inch diameter sphere is 452.39 square inches.The formula for surface area of a sphere is 4*pi*r2 where r=radius
60 inch diameter = 2.5 ft radius.Area = pi*r2= 19.6 sq feet.
If 36 inches is the diameter the answer is: 7,068 square feet.
