Awire of length 14 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 s and r
if we solve for s in 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 =
to obtain minimal area we should let r =
