A wire of length 28 m is to be cut into two pieces. One of the pieces is to be made into a square and the other into a circle. What should be the length of the two pieces so that the combined area of the square and the circle is minimum?

Question

$\begin{array}{1 1} \large\frac{-28\pi}{4+\pi} &\large\frac{112}{4+\pi} \\ \large\frac{28\pi}{4-\pi} &\large\frac{112}{4-\pi} \\ \large\frac{28\pi}{4+\pi} &\large\frac{112}{4+\pi} \\ \large\frac{28\pi}{4+\pi} &\large\frac{-112}{4+\pi} \end{array} $
