The volume of a cylinder is given by
[tex]V=\pi(R^2)H[/tex]Here H = 8cm, we do not know the value of the radius, but we can find that given the circumference.
[tex]\begin{gathered} C=2\pi R=20\pi \\ R=\frac{20\pi}{2\pi}=10\operatorname{cm} \end{gathered}[/tex]Thus the volume should be;
[tex]\begin{gathered} V=\pi(10^2)8 \\ V=2513.27\operatorname{cm}^3 \end{gathered}[/tex]That is option A
