Question

Someone pls help me with this

Answer 1

D.

Explanation:

The volume can be found by adding the volumes of a cylinder (the upper part of the figure) and a cone (the lower part of the figure).

Volume of Cylinder:
`V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}`

Volume of Cone: The height of the cone is 3 feet (the whole figure is 6 feet tall and the cylinder uses up 3 feet of that -- 6 - 3 = 3).

`V=(1)/(3)\pi r^2 h=(1)/(3)\pi(3^2)(3)=9\pi\approx 28.274`

The total volume is 84.823 + 28.274, about 113.1 cubic feet
