ANSWER
[tex]785.0[/tex]EXPPLANATION
Given;
[tex]\begin{gathered} r=5 \\ h=10 \end{gathered}[/tex]Recall, that the volume of a cylinder is calculated using;
[tex]\pi r^2h[/tex]Substituting the vales;
[tex]\begin{gathered} \pi r^{2}h \\ \pi=3.14 \\ A=3.14\times5^2\times10 \\ =3.14\times250 \\ =785.0 \end{gathered}[/tex]
