Hi there! So, there's -4 and that is being multiplied by -1/4, which is it's reciprocal, because it's -4 flipped over. It's definitely not C or D. There is no addition, so it's not B. The only answer that truly makes sense is A, so the answer is A.
Answer:
1767.1 inches cubed
Step-by-step explanation:
The volume of a ball, or a sphere, is:
, where r is the radius.
Here, the radius is r = 7.5. So, plug in this value: 
562.5 pi is about 1767.1 inches cubed.
Thus, the volume is 1767.1 inches cubed.
Hope this helps!
