Your question is not clear, if you are asking: what is

simplified? Then the answer is

.
If 63 is just the question number and you are asking, what is

simplified. Then the answer is

or

You get this answer by finding the highest number that both the numerator and denominator are divisible by, and diving both numbers by that:
C. 14.14 cu in.
V=4/3(3.14)r^3
V=4/3 (3.14)1.5^3
V=14.14
