Hmm... that's not making much sense to me. Do you mean:
If you do, you can start by plotting points. Then plot those points on graph paper. Find a point equal distances away from each of the points. That'll be your center. Then find the before mentioned distance. That'll be your radius.
If I interpreted that wrong, please let me know.
EDIT: If you need to do the second part algebraically, the number after the = is always the radius squared. Take the square root of that.
