Answer: Choice D

======================================================

Explanation:

The formula for the surface area of a cylinder is

[tex]SA = 2\pi*r^2 + 2\pi*r*h[/tex]

We then replace r with 10 and h with 25. Keep in mind that the diameter is 20 mm, so the radius is half that at 10 mm.

So that's how we get to

[tex]SA = 2\pi*10^2 + 2\pi*10*25[/tex]
