Step 1
Given;
[tex]\begin{gathered} A\text{ cylinder with radius 1.2mm} \\ Height=2mm \end{gathered}[/tex]
Required; To find the area
Step 2
The area of a cylinder is given as;
[tex]\begin{gathered} A=2\pi rh+2\pi r^2 \\ A=(2\times\pi\times1.2\times2)+(2\times\pi\times1.2^2) \\ A=4.8\pi+2\times\:1.2^2\pi \\ A=24.12743mm^2 \\ A\approx24.1mm^2 \end{gathered}[/tex]
Answer;
