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
