Answer
$V=0.5\pi$ cubic feet
Work Step by Step
The volume of a cylinder can be calculated as:
$V=r^2\pi h$ where r is the radius and h is the height.
Here, the diameter is given, but the radius is half the length:
$d=2r$
$d= 1$ ft
$r=0.5$ ft
The volume here is:
$V=0.5^2\times2\pi=0.5\pi$ cubic feet
