1) We've been told that this is a cylinder. So we can find out its volume by making use of this formula below:
[tex]V_{\text{cylinder}}=\pi\cdot r^2\cdot h[/tex]2) So let's plug into that the given information:
[tex]\begin{gathered} V_{\text{cylinder}}=\pi\cdot r^2\cdot h \\ V_{\text{cylinder}}=\pi\cdot(2)^2\cdot20 \\ V_{\text{cylinder}}=80\pi in^3 \\ V_{\text{cylinder}}\approx251.3in^3 \end{gathered}[/tex]3) Hence, the volume of that cylinder rounded off to the nearest tenth is 251.3 in³
