A Correct answer
Explanation

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

AI explanation

The formula for the volume of a sphere is V = (4/3) * pi * r^3. Substituting the radius of 3 cm into the formula gives V = (4/3) * pi * (3)^3. This simplifies to V = 4 * pi * 9, which equals 36pi cubic centimeters.
