Perimeter is adding all the sides up around the shape
well, if we look at the ring, the outer circle has a diameter of 3, that means its radius is half that or 1.5 or namely 3/2.
the radius of the inner circle will be that of the outer minus 1/8, namely 3/2 - 1/8 is the inner radius, or that is 11/8.
