Answer:
The second answer, and fifth answer
Step-by-step explanation:
we know that
the equation of the circle is of the form

where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have

so
the center is the point 
the radius is 
therefore
the answer is
The radius of the circle is equal to
