Given:
Height of the cylinder is, h = 18.2 cm.
Radius of the cylinder is, r = 3 cm.
The objective is to find the surface area of the cylinder.
The formula to find the surface area of the cylinder is,
[tex]SA=2\pi r^2+2\pi rh[/tex]
Now substitute the given values in the above equation.
[tex]\begin{gathered} SA=(2\cdot3.14\cdot3^2)+(2\cdot3.14\cdot3\cdot18.2) \\ =(2\cdot3.14\cdot9)+(2\cdot3.14\cdot3\cdot18.2) \\ =56.5+342.9 \\ =399.4cm^2 \end{gathered}[/tex]
Hence, option (B) is the correct answer.
