Three of the four vertices of a rectangle are $(5, 11)$, $(16, 11)$ and $(16, -2)$. What is the area of the intersection of this rectangular region and the region inside the graph of the equation $(x - 5)^2 + (y + 2)^2 = 9$? Express your answer as a common fraction in terms of pi.

The other vertex  of the rectangle is  the circle's center  =   (5, -2)


Look  at the image here :  



The region common to both areas is just  the quarter circle  area  of the given circle


And this circle has a radius  of 3.....so....the quarter circle has an area  of


pi (r^2)  / 4  =   pi (3^2)  / 4  =    (9/4)pi   units ^2
