Question

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

Answer 1

I think It's A

Explanation:

Answer 2

474.5 ft ³

Explanation:

1) Find the volume of the cube

`A=l^3` where l is the side length

Plug in 9 ft as l

`A=9^3\\A=729`

Therefore, the volume of the cube is 729 ft³.

2) Find the volume of the cylinder

`A=\pi r^2h` 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

`A=\pi (3)^2(9)\\A=\pi (9)(9)\\A=81\pi \\A=254.5`

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.

I hope this helps!
