Surface area of sphere: 4*pi*33^2 = 4356*pi square feet
The surface area of a sphere with a diameter of 18 feet is: 1,020 square feet.
The surface area of a sphere with a 24 inch diameter is 1809.6 square inches = 12.6 sq feet
The surface area of this sphere is 2,827 square feet.
A sphere having a diameter of 9.5 feet has a surface area of 283.53 square feet and a volume of 448.92 cubic feet.
The surface area is 1,020 square 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.
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.
It is: 4*pi*11.5squared = 529*pi square feet
The diameter would be 7.816 feet.
A sphere with 20 cubic feet of volume has the following:A radius of 1.684 feetA diameter of 3.368 feetA circumference of 10.58 feetA surface area of 35.63 square feet
256pi.
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)
