The wire 12 inches long is cut in 2 pieces, one length x and other 12-x. One piece is bent in shape of the circle and other a square.
a. Compute function which models area of both circle and square. Remember, x is circumference of circle and 12-xis perimeter of square.
(C = 2πr and A = πr^2 and P = 4s and A = s^2)
b. Determine value of x accurate to three decimal places which minimizes area.
