`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \pi (16)(12)\implies \pi \stackrel{ r }{(4^2)}\stackrel{ h }{(12)}\qquad \begin{cases} \textit{radius is 4, so}\\ \textit{diameter must be 8}\\ \textit{height is 12} \end{cases}`
