Hi Marv, so you need it tilted with parallel sides but is the top face of the cylinder supposed to be parallel to the main x/y plane?

You could create a regular vertical cylinder that's extended a bit, use Transform > Rotate to rotate it by 6.43 degrees and then draw in lines in a side view and cut the cylinder with those lines using boolean difference.

Or you could directly create a slanted cylinder from a base circle and slanted line by selecting the circle, running Extrude and then click the "Set path" button and then click the line. That will produce a different shape than a regular cylinder though, it will have an elliptical cross section through a plane normal to the line.
