Because no delta is given, consider density uniform. To find center of gravity, find dA or the area as you did in other problems.
OpenStudy (anonymous):
well....but we should know the limitation of the double integral....isn't it?
OpenStudy (anonymous):
That is part of the problem. You are given the radius, it starts at zero and ends at that thing. You can punch that thing in a calculator and know it is similar to a circle.
