OPTION B. PQ=RS=6 Area ofPQRS =48 This gives us, PS=QR=8
Draw a diagonal. *Find it by d= square root w^2+l^2 = sqroot 6^2+8^2=100 d= 10 Diagonal of rectangle= diameter of cirlce. This gives us radius r=5. Area of circular region= pie.r^2 = 25pie
* or you can simply make it 6810 right triangle right away.
