[AI-generated answer — Bot GPT 3.5]

First, we need to convert the diameter from centimeters to meters:

130 cm = 1.3 m

Now, we can find the radius of the cylinder:

radius = 1.3 m / 2 = 0.65 m

Next, we can find the surface area of the cylinder using the formula:

Surface area = 2πr(r + h)

Surface area = 2 * 3.14 * 0.65 * (0.65 + 12)

Surface area = 2 * 3.14 * 0.65 * 12.65

Surface area = 25.32 m2 * 12.65

Surface area ≈ 319.88 m2

Therefore, the surface area of the cylinder is approximately 319.88 m2.
