Answer:


\text{C. }x^2+(y+3)^2=11

Explanation:

The equation of a circle with radius
r and center
(h, k) is given by:


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

What we're given:

  • radius of
    √(11)
  • center at
    (0,-3)

Substituting given values, we get:


(x-0)^2+(y-(-3))^2=√(11)^2,\\\boxed{\text{C. }x^2+(y+3)^2=11}

D. I believe bc part of the equation is (y-y one) and y one is -3 and two negatives make a positive. And 11 squared it 121
