Step-by-step explanation:
The equation of a circle is
where
is the center of the circle and
is the radius of the circle.
Given that
and it passes
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:

Therefore, if the length of the radius is
units, then
, making the final equation of the circle
