Is the surface area and total area of a cylendar the same thing?

no

Step-by-step There is no difference between "total area" and "surface area" and your assertion that the "surface area" of a cylinder is 2pi rh is incorrect. That is the "lateral surface area". The ends of a cylinder are as much "surface" as the lateral surface

sorry man i accidentally pressed yes my bad

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
