Problem Statement
The figure is the intersection of circles (they may have different radii). Find the maximal number of curvilinear “sides” which can have. Curvilinear sides of are the arcs (of the given circumferences) that constitute the boundary of . (Their ends are the “vertices” of - the points of intersection of given circumferences that lie on the boundary of .)(N Brodsky)
