## 97. Math Puzzle $6 / 73$

Is there a cylinder whose surface area $O$ is twice the numerical value of its volume $V$, and where the numerical value of the circumference $U$ of the base equals the numerical value of its area $A$?

If yes, calculate the volume and surface area!
There is a cylinder of the required type. Its volume is $V=\pi r^{2} h=8 \pi$ cubic units, its surface area $O=2 \pi r(r+h)=16 \pi$ square units.
