hole array in cylinder

I need to make 2 rows of 25 square-ish air holes around both ends of a motor shell, a cylindrical wall. I've tried to apply hints from this forum but not very happy with my results. (Thanks Anna and Charles!)

I've been trying to understand 3D sketch but every time I try to make a point on the cylinder surface it actually apears along the centerline in another plane. This seems to imply that I would need 25 new plains to draw the holes. Is there a way to use the array feature to acomplish this or to make the holes?

An easier way might be to sketch it as a flat sheet metal part and bend it 360 degrees but how do I calculate matching length and diameter?

Thank you,
