The one in particular I'm havng problems with goes like this.
A wire 10 meters long is to be cut into 2 pieces. One piece will be shaped as an equilateral triangle, and the other piece will be shaped as a circle.
( the top quarter of the wire is 4x the bottom 3/4 is 10-4x)
a) Express the total area ,A, enclosed by the pieces of wire as a function of the length,x, of a side of the equilateral triangle.
I just need to know how to set it up. Everything else I can do. Thanks.
