Your sphere will have a surface area of about 201 square feet. The formula for finding the surface area (As) of a sphere is 4 times pi times the radius (r) squared, or this: As = 4 x pi x r2 That's As = 4 x 3.14 x 42 = 201.0619298 square feet. A link can be found for more information.

What is surface area of a sphere with the radius of 13 ft?
The surface area is 2,124 square feet.
What is the surface area of a sphere with a diameter of 6 feet?
1356.48 sq mt Another answer in square feet is : The formula for the surface area of a sphere is 4 x pi x radius squared. The radius is half the diameter, or 3 feet. The radius squared is therefore 9 square feet. The surface area is then 4x3.1415x9 square feet or 113.09 square feet.
What is surface square footage of 90' sphere?
The surface area of a sphere is (4 pi) x (radius of the sphere)-squared.We're not completely sure of what a "90' sphere" is. If you're saying that thesphere's diameter is 90-ft, then its radius is 45-ft, and its surface area is(4 pi) x (45-ft)-squared = 25,446.9 square feet, or 2,827.4 square yards. (both rounded)
What is the surface area of sphere with radius of 13 ft?
The surface area is 2,123.7 ft2
What is the surface of a sphere whose diameter is 17 feet?
Surface area of a sphere = 4*pi*radius2 The diameter is 17 feet so the radius is half of this i.e. 8.5 feet. 4*pi*8.52 = 907.9202769 square feet.
