Compare the last equation to
We see that h = 0, k = -2 and r = 5
So the center is (0, -2) and the radius is 5 units.

^2\ +\ (y\ -\ k)^2\ =\ r^2)
is the equation of a circle centered at )
with radius 
.
To answer your question, it will be convenient to re-write your equation thusly:
^2\ +\ \left(y\ -\ (-2)\right)^2\ =\ 5^2)
The answers you need are now available by inspection.
