Use the image to answer the question.
A cone is placed inside a cylinder. The apex of the cone touching the center of the top circle of the cylinder is highlighted with a dot. The cone with its base is drawn in dashed lines. The base of the cone is common with the base of the cylinder.
A sculptor created a design by carving a cone out of a cylinder. The cone and cylinder share the same radius and height. If the volume of the cylinder before removing the cone is 54 in.3 , what is the volume of the amount remaining?(1 point)

The volume of a cone is (1/3)πr^2h and the volume of a cylinder is πr^2h, where r is the radius and h is the height.
Since the cone and cylinder share the same radius and height, the volume of the cone is (1/3)πr^2h and the volume of the cylinder is πr^2h.
Given that the volume of the cylinder before removing the cone is 54 in.3, the volume of the cone is (1/3) × 54 = 18 in.3.
The volume of the remaining amount after carving out the cone is 54 - 18 = 36 in.3.
Therefore, the correct answer is:
36 in.3
