The tricky part is that imfindcircles gets confused between the inner white circle and the boundary. How do I use edge detect on just the black circle ? I would like to completely transform this image into pure black and white image so that I can use imfindcircles to get the answers. Any advise is appreciated.

Just get rid of them:
% Invert mask so black is white.
mask = ~mask;
% Fill holes
mask = imfill(mask, 'holes');
No need to invert again and turn your object black since MATLAB only considers the white blobs when doing operations.
