Answer :
STEP 1
Identify what is required and allocate data rightfully.
Height = 8cm
Radius = 4cm
The surface area of a cylinder is given as
[tex]2\pi r^2+2\pi rh[/tex]where r is radius and h is height.
STEP 2
We get the surface area for this particular cylinder as
[tex]\begin{gathered} 2\pi\times4^2+2\pi\times4\times8 \\ =32\pi+64\pi\text{ = 96}\pi=301.593cm^2 \end{gathered}[/tex]SURFACE AREA = 301.6 sq cm
