Why does this formula work for finding the surface area of a cylinder?

In math class today, we were discussing how to find the surface area of a cylinder. Then, someone figured out that you could use the formula (radius+height)(diameter). We tested the formula and it worked for every problem we had.
Why does this work or is it just a loophole?

I can about guarantee the class is confusing diameter (thinking perimeter) and circumference.
