a piece of wire 11 ft long is cut into two pieces. One piece is made into a circle and the other piece is made into a square. Let the piece of length x be formed into a circle. Allow x to equal 0 or 11, so all the wire is used for the square of for the circle. How long should each piece of the wire be to minimize the total area? What is the radius of the circle? How long is each side of the square?
