First I will give you the practical application.
I am trying to figure out the formula for finding the diameter of a cable that is made up of various size wires.
In math terms:
I have 8 circles that have a diameter of .04", I have 4 circles that have a diameter of .10" and I have 1 circle that has a diameter of .13".
I am trying to find the formula for figuring out what the diameter is of the smallest circle that all of the above circles could fit in.
I know how to figure it out if all the circles where the same size:
N=NUMBER OF CIRCLES
A= AREA OF ONE CIRCLE
This works if all circles are the same, but I am not sure how to handle it if there are different size circles.
