The radius of the circle is the distance between the center and the y-intercept.
The radius of the circle is 4 units
How to determine the radius
The given parameters are:
Center = (0,3)
Y-intercept = (0,7)
The radius is calculated as:
[tex]r = \sqrt{(0 - 0)^2 + (3 - 7)^2}[/tex]
Evaluate
[tex]r = \sqrt{16}[/tex]
Solve
[tex]r =4[/tex]
Hence, the radius of the circle is 4 units
