Sagot :

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
