Answer: Choice D
======================================================
Explanation:
The formula for the surface area of a cylinder is
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
6h+1-h+3
=5h+4
because 6h-1h is 5h and 1+3 is 4
