A piece of wire 18 m long is cut into two pieces. One piece is bent into a square and the other is bent into a circle.
(a) How much wire should be used for the square in order to maximize the total area?

If x is allocated to the square, that leaves 18x for the circle. So,
r = (18x)/2π
a = π((18x)/2π)^2 + (x/4)^2
= (1/4π + 1/16)x^2  9/π x + 81/π
now just set da/dx=0 and solve for x
