To find the surface area of the cylinder, we need to know the radius and height. Let's assume the radius is 5 cm and the height is 8 cm.
SA = 2πr^2 + 2πrh
SA = 2 * 3.14 * 5^2 + 2 * 3.14 * 5 * 8
SA = 2 * 3.14 * 25 + 2 * 3.14 * 40
SA = 157 + 251.2
SA = 408.2 cm^2
Therefore, the surface area of the cylinder is 408.2 cm^2. Rounding to the nearest tenth, the answer is 408.2 cm^2.
