<u>2) Find the volume of the cylinder</u>
where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
<u>3) Subtract the volume of the cylinder from the volume of the cube</u>
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.
