Explanation:

Step1: Recall surface area formula

The total surface area of a cylinder is given by:
$$SA = 2\pi r^2 + 2\pi r h$$
where $r$ is the radius, and $h$ is the height.

Step2: Substitute given values

$r = 4$ cm, $h = 2$ cm, $\pi = 3.14$
First calculate the area of the two circular bases:
$$2\pi r^2 = 2 \times 3.14 \times 4^2 = 2 \times 3.14 \times 16 = 100.48$$
Then calculate the lateral surface area:
$$2\pi r h = 2 \times 3.14 \times 4 \times 2 = 50.24$$

Step3: Sum the two areas

Add the base area and lateral area to get total surface area:
$$SA = 100.48 + 50.24$$

Answer:

150.72 square centimeters
