1) Let's find out the height of that cylinder, by plugging it into the formula:


\begin{gathered} V=\pi\cdot r^2\cdot h \\ 198\text{ =}\pi\cdot rh \\ \end{gathered}

2) The Base area is given by:


\begin{gathered} A_B=\pi\cdot r^2 \\ 22=\pi\cdot r^2 \\ (22)/(\pi)=(\pi)/(\pi)r^2 \\ r=\sqrt[]{(22)/(\pi)} \end{gathered}

So now let's plug that radius


undefined
