The answer is 72 cubic inches. This is because the formula for the volume of a cylinder is πr² × h, and the formula for the volume of a cone is (πr² × h)/3. This means that the volume of a cone with the same height and radius as the cylinder will just be a third of the volume of the cylinder, so we need to divide 216 by 3 which equals 72.
I hope this helps!
