A sphere with 3-ft diameter has about 0.4 cubic metre of volume.
a. 2 to 5.
3 ft
The sphere's approximate volume is 523.6 cubic feet.
The volume of a sphere with a radius of 32 feet is about 137,258.3 feet3

113.097336 cubic 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)
The volume is 137,260 cubic feet.
Volume = 301592894.7 cubic feet
The surface area is 2,123.7 ft2
