From the problem, we have an object that is composed of a cylinder and a cone.

The volume formula of a cylinder is :


V=\pi r^2h_1

and the volume formula of a cone is :


V=(\pi r^2h_2)/(3)

The total volume will be the sum of these volumes.


V=\pi r^2h_1+(\pi r^2h_2)/(3)

From the problem, the cylinder has a radius of r = 2 cm and the height is h1 = 7 cm.

The cone has a radius of r = 2 cm and the height is h2 = 6 cm

Using the formula above, use π = 3.


\begin{gathered} V=3(2)^2(7)+(3(2)^2(6))/(3) \\ V=84+24 \\ V=108 \end{gathered}

The answer is 108 cm^3
