Suppose I am plotting random circles like in the following example: m=125;
g10=Graphics[{Table[Circle[pt[i],r],{i,m}]},Axes->True,PlotRange->{{-5000,5000},{-5000,5000}}]
g10=Graphics[{Table[Circle[pt[i],r],{i,m}]},Axes-
>True,PlotRange->{{-5000,5000},{-5000,5000}}]
Some of the circles may overlap. How can I calculate the whole overlapped area (Integrate it) and the ratio of this overlapped area to the integrated circles area (Here 125Pir2)?
