Answer:

D  36πa^6b^9

Step-by-step explanation:

Step 1. Write the formula for the volume of a sphere.

V = (4/3)πr³

Step 2. Replace r with the given radius. Since the given radius is an expression, remember to enclose it in parentheses and cube the entire expression.

V = (4/3)π(3a²b³)³

Step 3. Simplify the expression. Start by cubing each factor inside the parentheses.

V = (4/3)π ×(3)³(a²)³(b³)³

To raise an exponent to an exponent, multiply the exponents.

V = (4/3)π × 27a^6b^9

V = (4/3 × 27)πa^6b^9

V = 36πa^6b^9

Answer: D  36πa^6b^9
