Answer:
C.
Step-by-step explanation:
According to the volume equation of a sphere (V=4/3πr³)
8.4/2 equals a radius of 4.2, which when cubed equals 74.088 (base area). You then multiply your base area by the numerator of 4/3, giving you 296 when rounded or 296.352 when not rounded. Giving you the answer of C.
