When you divide these, factor both the numerator and the denominator to see if anything cancels out. That's the best way to do it. Easier than long division of polynomials, although it can also be done that way. Factoring both the numerator and denominator gives you this: 
. The (x-2) factor cancels out in the top and bottom leaving you with just 
. That's your answer.

Step-by-step explanation:
remember. the radius is always half the diameter.
volume of a cylinder
pi × r² × height
pi×7.5²×48 = pi×56.25×48 = 8,482.300165... in³
volume of a sphere
4/3 × pi × r³
and that volume should be the same as the cylinder. so,
4/3 × pi × r³ = pi×56.25×48
4/3 × r³ = 56.25 × 48
1/3 × r³ = 56.25 × 12
r³ = 56.25 × 36 = 7.5² × 6² = (7.5×6)² = 45² = 2025
which would be 12.65148998... in.
