Identify the volume of the composite figure. Round to the nearest tenth.

474.5 ft ³

Step-by-step explanation:

1) Find the volume of the cube

where l is the side length

Plug in 9 ft as l

Therefore, the volume of the cube is 729 ft³.

2) Find the volume of the cylinder

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.

3) Subtract the volume of the cylinder from the volume of the cube

729 ft³ - 254.5 ft ³

= 474.5 ft ³

Therefore, the volume of the figure is 474.5 ft ³.
