Surface area = 4*pi*82 = 804.248 square feet rounded to 3 dp
Surface Area = 572.56 ft2
The surface area of a sphere is 4 x Pi x radius2. Pi = 3.142. If you want the answer in sq ft you have to measure the radius (half the diameter) in feet.
The sphere's approximate volume is 523.6 cubic feet.
The area of a circle with a diameter of 8 feet is: 50.27 square feet.
The surface area is 1,020 square 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 of a sphere with a 24 inch diameter is 1809.6 square inches = 12.6 sq 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.
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 sphere: 4*pi*33^2 = 4356*pi square feet
Surface area = 4*pi*82 = 804.248 square feet rounded to 3 dp
Surface area = 4*pi*radius2 = 50.265 square feet correct to 3 dp
It is: 4*pi*11.5squared = 529*pi square feet
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)
Surface area of a sphere = (4 pi) (Radius)2 Radius = 1/2 diameter = 36.5-ft Surface area = (4 pi) x (36.5)2 = 16,741.5 square feet (rounded) = 1,860.2 square yards (rounded)
