SOLUTION
Given the figure in the image on the question tab;
Explanation;
The composite figure is made up of a cylinder and a hemisphere.
[tex]\begin{gathered} Volume\text{ of cylinder=}\pi r^2h \\ Volume\text{ of hemisphere= }\frac{2}{3}\pi r^3 \end{gathered}[/tex]Therefore, the volume of the composite figure is:
[tex]\pi r^2h+\frac{2}{3}\pi r^3[/tex]Final answer:
