Answer:
C
Step-by-step explanation:
The vertex form of the equation of a circle is
where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes
. This simplifies to
. The solution is C.
