Homework Statement
If Dr is a closed disk of radius r centered at (a,b) find lim r->0 (1/pir2) [tex]\int\int[/tex]fdA over Dr.
The Attempt at a Solution
From mean value equality, [tex]\int\int[/tex] fdA = f(x,y)A(D) where A(D) is the area of the region which here is pir2. So the lhs becomes lim r->0 f(x,y). Where do I go from here?
