D Correct answer
Explanation

Volume of a sphere = (4/3) * pi * r^3. With r = 3, Volume = (4/3) * pi * 27 = 4 * pi * 9 = 36pi.

AI explanation

Using the volume of a sphere formula V = (4/3) * pi * r^3, we substitute the given radius of 3 cm. This yields (4/3) * pi * 3^3, which simplifies to 4 * pi * 9. The result is 36 * pi cm^3.
