Finding the Volume of a Figure with a Hollowed Out Section

To find the volume of a figure with a hollowed out section, you can calculate the volume of the entire figure and then subtract the volume of the hollowed out section.

Step 1: Calculate the Volume of the Entire Figure - If the figure is a cylinder with a hollowed out section, the formula for the volume of a cylinder is V = πr^2h, where r is the radius of the base and h is the height of the cylinder.

Step 2: Calculate the Volume of the Hollowed Out Section - If the hollowed out section is a cylinder, you can use the same formula to calculate its volume: V = πr^2h.

Step 3: Subtract the Volume of the Hollowed Out Section from the Volume of the Entire Figure - Once you have the volumes of the entire figure and the hollowed out section, you can subtract the volume of the hollowed out section from the volume of the entire figure to find the final volume.

For other types of figures with hollowed out sections, similar principles can be applied to calculate the volume.
