Standard equation for a circle centered at a point (h,k) is
Note that diameter .
The first circle centered at the origin is .
Your next two circles work this way.
The diameter of 20 means that r=10, so this circle, centered at origin is .
The last circle of diamter 15 has , and based on its given center,
or
