Answer :
hello,
to resolve this issue we must calculate the volume of the drum (cylinder).
Let's use the formula below:
[tex]\begin{gathered} V\text{ = }\pi\cdot r^2\cdot\text{ height} \\ V\text{ = 3.14 }\cdot4^2\cdot\text{ 4.5} \\ V\text{ = 3.14 }\cdot\text{ 16 }\cdot\text{ 4.5} \\ V\text{ = }226.08feet^3 \end{gathered}[/tex]So, the volume is equal to 226.08feet³.
