Option A. 54.008 cubic feet

Step-by-step explanation:

we know that

The volume of the barrel is equal to

$V=\pi r^{2}h$ ----> volume of the cylinder

we have

$r=4/2=2\ ft$ ----> the radius is half the diameter

$h=4.3\ ft$ ---> is the depth

$\pi =3.14$

substitute

$V=(3.14)(2)^{2}(4.3)$

$V=54.008\ ft^{3}$
