The volume (V) of a cylinder is:
[tex]V=Ab*h[/tex]Where:
h = height of the cylinder
Ab = area of the base
[tex]Ab=\pi r^2[/tex]Where:
r = radius of the base
Then,
[tex]V=\pi r^2h[/tex]In this question,
r = 8.5 ft
h = 36 ft
Then,
[tex]\begin{gathered} V=\pi *8.5^2*36 \\ V=\pi *72.25*36 \\ V=2601\pi \\ \text{ Using }\pi=3.14 \\ V=2601*3.14 \\ V=8167\text{ ft}^3 \end{gathered}[/tex]Answer: 8167 ft³.
