In order to calculate the volume of a cylinder, we can use the following formula:


V=\pi r^2h

Where r is the base radius and h is the height.

If the circumference is 8, we have:


\begin{gathered} C=2\pi r \\ 8=2\pi r \\ r=(4)/(\pi) \end{gathered}

Now, calculating the volume, we have:


\begin{gathered} V=\pi((4)/(\pi))^2\cdot10 \\ V=(160)/(\pi) \\ V=50.93 \end{gathered}

So the correct option is the second one.
