Answer:
48,970.7 in³
Step-by-step explanation:
If the diameter is 57.2 in, then the radius is half that, or 28.6 in.
The volume of a sphere is V = (4/3)πr³, and so the volume of this hemisphere is (2/3)πr³.
Substituting 28.6 in for r, we get the final answer:
(2/3)(3.14)(28.6)³ in³, or (to the nearest tenth of a cubic inch), 48,970.7 in³
