c1=396
c2=374
area of the ring = 22/7×(396×7/22)^2-22/7×(374×7/22)^2
=5390
c2=374
area of the ring = 22/7×(396×7/22)^2-22/7×(374×7/22)^2
=5390
its wrong

First of all you take out the radius of both concentric circles .Then, find the area of both the circles and at last minus the area of second concentric circle from the first concentric circle.
That will be the area of the shaded portion.
Hope this will help you!!!
