Either the inner circle is irrelevant to the problem; or you have left something out of the statement of the problem.

A segment of a circle of radius 6 that is determined by a central angle of 312 degrees has an area that is 312/360 of the area of the whole circle.

Regarding this post, I have two notes/comments. 

1.  The "arc" as a geometric object DOES NOT HAVE AREA.

    The notion AREA is not determined/defined for "arc".



2.  Mathematically, this formulation is totally dark and MAKES NO SENSE.
