To find the surface area of the cylinder, we need to know the radius (r) and height (h) of the cylinder.

Let's assume r = 5 cm and h = 10 cm.

Substitute these values into the formula:

SA = 2 * 3.14 * 5^2 + 2 * 3.14 * 5 * 10
SA = 2 * 3.14 * 25 + 2 * 3.14 * 50
SA = 157 + 314
SA = 471

Therefore, the surface area of the cylinder is 471 cm^2. Rounding to the nearest tenth, the answer is 471.0 cm^2.

I apologize for the error in my previous response. Let's correct that.

Given that the radius (r) is 5 cm and height (h) is 10 cm, let's calculate the surface area using the formula:

SA = 2πr^2 + 2πrh
SA = 2*3.14*5^2 + 2*3.14*5*10
SA = 2*3.14*25 + 2*3.14*50
SA = 157 + 314
SA = 471 cm^2

Therefore, the correct surface area of the cylinder is 471 cm^2. Rounding to the nearest tenth, the answer is 471.0 cm^2. Thank you for your patience.
