Answer:
D.
Step-by-step 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: [tex]V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}[/tex]
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).
[tex]V=\frac{1}{3}\pi r^2 h=\frac{1}{3}\pi(3^2)(3)=9\pi\approx 28.274[/tex]
The total volume is 84.823 + 28.274, about 113.1 cubic feet
