I don’t think I under stand the question. If it is sheet it is 3" x15". If you are figuring square inches and that is a perfect circle you have two straight pieces 1" x 13.5" and circle with a 3" with a circle of 1" diameter removed from the larger circle and the remaining square inches of the 3" circle city in half. There probably is a formula but I tend to be a 3D hands on mechanical sample kind of guy.
If it’s tubing get 3’ of 1" soft copper, bend it, city off the extra, straighten it and measure it.
That’s what I’d do but then I often miss the obvious.
