Beyond the Answer
The radius of the circle can be determined by calculating the distance between the center
and the point
. Using the distance formula:
Substituting in the coordinates of
and
:
Now that we have the radius
, the equation of the circle can be expressed as:
Next, we will check where the point
lies in relation to this circle by substituting
's coordinates into the circle’s equation:
Since the left-hand side equals the radius squared (85), the point
lies on the circle!
