A Correct answer
Explanation

Volume of a sphere = (4/3) * pi * r^3. With r = 3, V = (4/3) * 3.14 * 27 = 4 * 3.14 * 9 = 113.04. Option A is the closest.

AI explanation

Using the formula for the volume of a sphere, V = 4/3 * pi * r^3, we substitute r = 3 cm. This gives V = 4/3 * 3.1416 * 3 * 3 * 3, which equals 113.097 cm^3. Rounding to two decimal places, the volume is 113.14 cm^3.
