Answer 2

Answer: Choice D

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

Step-by-step explanation:

The formula for the surface area of a cylinder is

`SA = 2\pi*r^2 + 2\pi*r*h`

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

`SA = 2\pi*10^2 + 2\pi*10*25`
