Answer:

314 ft cubed

Step-by-step explanation:

To find the volume, find the volume of the cone and add it to the volume of the cylinder.

The volume of a cone is

$V= \frac{1}{3}\pi r^2 h= \frac{1}{3}\pi (5^2)(12) = \frac{1}{3}\pi (25)(12)= \frac{1}{3}\pi *300 = 100\pi$ .

The volume of the cylinder is

$V=\pi (5^2)(4)= \pi (25)(4)= 100\pi$

Together their volume is $100\pi+100\pi=200\pi \\200\pi =314ft^3$
