What’s the radius of each circle x^2+(y-3)^2=25

Radius = 5.

Step-by-step explanation:

Compare this with the following general form of a circle:

(x - h)^2 + (y - k)^2 = r^2

x^2        + (y - 3)^2  = 25

We see that the radius (r) =  sqrt 25 = 5.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
