Answer :

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

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

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
