112π cubic inches
288π cubic inches
290π cubic inches
300π cubic inches

i am not good with pi

Answer 1

The answer is (B).
If we substitute r = 6 inches into the volume of a sphere formula we get this:
π6³
Since 6³ = 216, we multiply this by 1.3333 to get 288. If we multiply this by pi we get 288π, or (B).
