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

To solve the problem, we first need to find the volume of the cone that has been carved out of the cylinder.

  1. Volume of the Cylinder (V_c):
    The volume of a cylinder is given by the formula: \[ V_c = \pi r^2 h \] According to the problem, the volume of the cylinder before removing the cone is \(54 , \text{in}^3\).

  2. Volume of the Cone (V_cone):
    The volume of a cone is given by the formula: \[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \] Since the cone has the same radius and height as the cylinder, the volume of the cone will be: \[ V_{\text{cone}} = \frac{1}{3} V_c = \frac{1}{3} \times 54 , \text{in}^3 = 18 , \text{in}^3 \]

  3. Volume Remaining After Carving the Cone:
    To find the volume remaining in the cylinder after the cone has been removed, we subtract the volume of the cone from the volume of the cylinder: \[ V_{\text{remaining}} = V_c - V_{\text{cone}} = 54 , \text{in}^3 - 18 , \text{in}^3 = 36 , \text{in}^3 \]

Thus, the volume of the amount remaining after the cone has been removed is 36 in.³.
