I want to cut an oval hole in a piece of sheet metal that will be round when I roll the sheet metal into a 1 3/4" I.D. tube. The short dimension of the oval will be 1 3/4", but what will the long dimension be? (Assume the sheet metal has a zero thickness.) Will it be half the circumference?
I guess this is a math problem. Thanks.
