Answer:

37.7cm²

Step-by-step explanation:

The surface area of a cylinder is calculated using the formula below:

$SA=2\pi r(r+h)$

From the given figure:

• The height of the cylinder = 1cm

,

• The radius of the cylinder = 4/2 = 2cm

Therefore:

$\begin{gathered} SA=2*\pi*2(2+1) \\ =4*3*\pi \\ =12*(22)/(7) \\ =37.7\operatorname{cm}^2 \end{gathered}$

The surface area is 37.7cm² (to the nearest tenth).
