The standard equation of a circle in the coordinate plane is given by:
\[
(x - h)^2 + (y - k)^2 = r^2
\]
where \((h, k)\) is the center of the circle and \(r\) is the radius.
From the provided information, we have:
- The center \((h, k) = (0, 3)\)
- The radius \(r = 3\)
Substituting the center and radius into the standard equation of the circle, we get:
\[
(x - 0)^2 + (y - 3)^2 = 3^2
\]
Simplifying, we find:
\[
(x - 0)^2 + (y - 3)^2 = 9
\]
So, filling in the missing information in your equation:
\[
(x - 0)^2 + (y - 3)^2 = 9
\]
Thus, the filled-in equation is:
\[
(x - 0)^2 + (y - 3)^2 = 9
\]
\[
(x - h)^2 + (y - k)^2 = r^2
\]
where \((h, k)\) is the center of the circle and \(r\) is the radius.
