Answer:

Option A. 54.008 cubic feet

Step-by-step explanation:

we know that

The volume of the barrel is equal to

[tex]V=\pi r^{2}h[/tex] ----> volume of the cylinder

we have

[tex]r=4/2=2\ ft[/tex] ----> the radius is half the diameter

[tex]h=4.3\ ft[/tex] ---> is the depth

[tex]\pi =3.14[/tex]

substitute

[tex]V=(3.14)(2)^{2}(4.3)[/tex]

[tex]V=54.008\ ft^{3}[/tex]
