In order to calculate the lateral area of the cylinder, we can use the formula:
[tex]S=2\pi rh[/tex]
The diameter of the cylinder is 4 meters, so the radius is 2 meters. Also, the height is 12 meters, so we have:
[tex]\begin{gathered} S=2\pi\cdot2\cdot12 \\ S=48\pi \\ S=150.8 \end{gathered}[/tex]
Rounding to the nearest whole number, the lateral area is 151 m².
