Answer:

$\large\boxed{V\approx150.72\ ft^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the height H = 3ft and the radius r = 4ft. Substitute:

$V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3$

$\pi\approx3.14$

$V\approx48(3.14)=150.72\ ft^3$
