I tried making an equation using their cirmcumferences but I was way off. All I did was subtract the inner circle's circumference from the outer circle's circumference and set it equal to the distance between them and I know that would never work

**Reiny**, Sunday, October 11, 2009 at 2:15pmNot too sure if I understand the question correctly"the distance between them" ?

who is the "them", the circles ?

e.g. radius of first circle = 8

radius of second circle = 3

difference between them is 5

So the distance between them is the difference of the two radii.
