Answer:
[tex]\large\boxed{V\approx150.72\ ft^3}[/tex]
Step-by-step explanation:
The formula of a volume of a cylinder:
[tex]V=\pi r^2H[/tex]
r - radius
H - height
We have the height H = 3ft and the radius r = 4ft. Substitute:
[tex]V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3[/tex]
[tex]\pi\approx3.14[/tex]
[tex]V\approx48(3.14)=150.72\ ft^3[/tex]
