Math Is Fun Forum

I have a question that I cant get, help is much appreciated! Thanks in advance!

A wire 60in long is cut into 2 pieces (if optimal).  One of the pieces will be bent into the shape of a circle.  The other will be bent into the shape of an equilateral triangle.  Where should the wire be cut so the sum of the areas is a) a maximum, b) a minimum.

Thanks!!
