the volume of a cylinder is 1269 pi cm^3 and its height is 16 cmthe length of the cylinders radius is ___ cm

The volume of cylinder is.
[tex]V=1296\pi[/tex]The height of cylinder is h = 16.
The formula for the volume of the cylinder is,
[tex]V=\pi(r)^2h[/tex]Determine the length of radius of cylinder.
[tex]\begin{gathered} 1296\pi=\pi(r)^216 \\ r^2=\frac{1296\pi}{16\pi} \\ =81 \\ r=\sqrt[]{81} \\ =9 \end{gathered}[/tex]So length of cylinder radius is 9 cm.
