Answer:

Step-by-step explanation:
The equation of a circle with center at (h, k) and radius r is

You have center (0, 4).
We get:


To find the radius, we use the distance formula to find the distance from the center of the circle to the given point on the circle.





We need r^2 in the equation of the circle, so

The equation of the circle is

Factor this and set equal to zero to get
0 = (4x+ 5)(x-3)
x = 3 and -5/4
