Answer:
b. 6280 cubic feet
Step-by-step explanation:
Volume:
The volume of the prism, which has a cylindrical base, with radius r and height h, is given by:
[tex]V = \pi r^2h[/tex]
Radius:
The radius is 20, so [tex]r = 20[/tex]
The manufacture recommends that it be filled to within 1 foot of the rim.
Height of 6 - 1 = 5, so [tex]h = 5[/tex]
Then
[tex]V = 3.14*(20)^2*5 = 6280[/tex]
So the volume is 6280 cubic feet, and the correct answer is given by option b.
