A cylindrical pressure vessel has a height of 9 feet and a diameter of 6 feet. How much gas can the pressure vessel hold when full? A. 54π cubic feetB. 81π cubic feet C. 108π cubic feetD. 324π cubic feet

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}
