Answer :
Hi There ^^
Answer :- ( B ) 81 π cubic feet
Explaination :-
[tex]We \: \: are \: \: given \: \: that \\ \\ \:
\: Height \: = \: 9 \: feet \\ \\
Diameter \: = \: 6 \: feet \\ \\
radius = 3 feet \\
\\ \\ Volume \: \: = \pi {r}^{2} h \\ \\ = \pi \times 3 \times 3 \times 9 \\ \\ = 81\pi \: {feet}^{3}
[/tex]
Thanks

Answer: B. 81π cubic feet
Step-by-step explanation:
The equation for cylinders V = π * r² * h
Plug in the numbers r = radius which is half of the diameter and h = height. Also leave out π because of the answer choices.
so... 3² * 9 = 81
81π
