A wire of length 18 is cut into two pieces which are then bent into the shape of a circle of radius and a square of side . Then the total area enclosed by the circle and square is the following function of and is .
If we solve for in terms of , we can reexpress this area as the following function of alone:_____________.
Thus we find that to obtain maximal area we should let
To obtain minimal area we should let
