Aware of length 7 is cut into two pieces which are then bent into the shape of a circle of radius r and a square of side s. Then the total area enclosed by the circle and square is the following function of sandr If we sole for sin terms of r we can reexpress this area as the following function of r alone: Thus we find that to obtain maximal area we should let r = Yo obtain minimal area we should let r = Note: You can earn partial credit on this problem
