what is the radius of the circle with the following equation?

x^2 + (y-3)^2=121

The circle's center points are (0,3) and the radius is 11

Step-by-step explanation:

the 3rd on is correct

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
