Find the volume of this composite solid.

For this case we have that the figure shown is composed of a cylinder and a cone.

We have that the volume of a cylinder is given by:

Where:

A: It's the radio

h: It's the height

Substituting the values:

On the other hand, the volume of a cone is given by:

Where:

A: It's the radio

h: It's the height

Substituting the values:

Then, the total volume is:

Taking , we have to:
