If you're looking to determine a circle by using a central point and another point, two crucial pieces of information are required: the center coordinates, denoted as (h,k), and the coordinates of the point that resides on the circle, represented as (x,y). The radius of the circle is essentially the distance between these two points. To solve this, apply the equation for a circle, which is (x-h)²+(y-k)²=r².
