Given:
The radius, r=4cm.
The height, h=9cm.
To find the surface area of the cylinder:
The surface area of the cylinder is,
[tex]\begin{gathered} A=2\pi rh+2\pi r^2 \\ =2\pi\times4\times9+2\pi\times4^2 \\ =72\pi+32\pi \\ =104\pi cm^2 \end{gathered}[/tex]
Thus, the surface area of the cylinder is,
[tex]104\pi cm^2[/tex]
