The equation for a circle is as followed:
where the center of the circle is at (h,k) and the radius of the circle is r.
We are given (h,k) and need to find the radius. To do so, we can use the distance formula to find the distance from the center to the point on the circle:
Plug in the two points:
If the distance from the center to the edge of the circle is the square root of 117, then r^2 = 117.
