the answer is the third one
The correct answer is 43.75
Step-by-step explanation:
.................. Rotation
If your equation is

, then the domain is all real numbers (-∞, ∞).
If your equation is

,
then the domain is all real numbers except zero (-∞, 0)∪(0, ∞)
so you subtitute and get SA=2(2)2+4(2)(4) and get SA=8+32=40
actually the surface area is 2(s^2)+4sh and if you subitute you get the same thing
