Answer:
[tex]4022.9[/tex]
Step-by-step explanation:
Volume of a cylinder is given by cross sectional area multiplied by height hence
V=Ah
Since the cross sectional area of
[tex]A=\pi r^{2}[/tex]
Substituting the formula for A into formula for volume then
[tex]V=Ah=\pi r^{2}h[/tex]
Substituting 8ft for r and 20 ft for h then
[tex]V=Ah=\pi 8^{2}\times 20=4022.8571428571\ ft^{3}\approx 4022.9\ ft^{3}[/tex]
Rounded off to the nearest tenths, the volume is equivalent to
[tex]4022.9[/tex]
