V = ⁴/₃πr³
V = ⁴/₃(3.14)(28)³
V = ⁴/₃(3.14)(21,952)
V = ⁴/₃(68,929.28)
V = 91,905.70667cm³
V ≈ 92,000cm³

Depends on what 28 cm is. The radius? The diameter?

Assuming it's the radius, using the formula for the volume of a sphere (
4/3 r^3 \pi), we get about 91,952 cubic centimeters, which is closest to 92,000.
