Okay, so I think you calculated the volume of the cylinder, not its surface area.

No matter how you look at it a cylinder does not care what kind of caps you put on it. Its just pi * D * L or 3.14 * 8 * 40
This assumes no corrections for the thickness of the wall since a flat piece of metal will not join with the two ends exactly parallel. You learn this when you make thick wall pipe or steel rings.
8 x π = 25.13274 x 40 = 1,005.31
In quoting my post, you affirm and agree that you have not been goaded, provoked, emotionally manipulated or otherwise coerced into responding.
