If I undertand what you mean, then
>>>by "origin" you mean the center of the circle.
>>>You want to find the center of the second (and bigger) circle by finding the disdtance, d, between the two centers.
Try giving us the locations of the center of the first (and smaller) circle, and of the two points P1 and P2, and the radius of the second circle, so we might help you find "d" and the location of the center of the 2nd circle based on the location of the 1st circle.
I can show you the way to find "d" even if you don't show us the locations of the said 3 points and the dimension of the bigger radius. But it is easier to explain with numbers.
