D Correct answer
Explanation

Volume of a cone = (1/3) * pi * r^2 * h. Volume = (1/3) * (22/7) * 3^2 * 7 = (1/3) * 22 * 9 = 66 cm^3.

AI explanation

The volume of a cone is calculated using the formula V equals 1/3 times pi times r squared times height. Substituting the given values into the formula gives 1/3 times 22/7 times 3 squared times 7, which simplifies to 1/3 times 22/7 times 9 times 7. Performing the multiplication and division results in a volume of 66 cubic centimeters, corresponding to option C.
