The answer to this question is 5. The radius of the circle is 5 as the square root of the constant r in (x-h)^2+(y-k)^2=r^2 gets you the radius.

The standard equation of a circle is:

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

where (h, k) is the center, and r is the radius.

Since you have r^2 = 25, then r = 5, so the radius is 5
