Question

Which of the following formulas will assist you in calculating the surface area of a cylinder?

SA = 2lw + 2wh + 2lh
SA = 2(pi)h + 2(pi)2
SA = 4(pi)2
SA = (pi)r + (pi)r2

Answer 1

i am working on this SA = 2rh + 2r2

Explanation:

Answer 2

The actual answer is: SA = 2rh + 2r2

The answer is not SA = 2lw + 2wh + 2lh, the other guy has it incorrect. I put his answer in an assignment and I got it wrong. Trust me, the correct answer is SA = 2rh + 2r2.
