Hmmm... In my question R=7, Theta=18. Does your answer gives a different result for your values than mine does?
I disagree that the result I got is length though. Are you basing this on the fact that the answer only contains R^1? Yes this does seem odd now that I think about it, but I still think that the result gives the correct area because what I defined was a summation of lengths, which results in an area (or a length equivalent to the area, if you want to look at it that way). The integral I think, makes sense. The answer not so much but it does give the correct result, odd as it may seem. As for the coordinates I accounted for the coordinates' input with the expression of the circle's circumference, so yes what I said is a bit incorrect since the jacobian did play a role, I just wrote its result without explicitly calculating it.
