87.96 square mm, using 3.14 as pi
For surface area of a cylinder:
A = 2(pi)(radius)(height) + 2(pi)(radius squared)
For the first half of that equation:
2(pi)(radius)(height)
2(3.14)(2)(5)
= 62.8
Now the second half of that equation, the area of the circle ends:
2(pi)(radius squared)
= 2(3.14)(2)(2)
= 25.12
Add them up:
62.8 + 25.12 = 87.92
