Answer:
The center of the circle is

Step-by-step explanation:
Let the equation of the circle be
, where (-a,-b) is the center of this circle.
The points lying the circle must satisfy the equation of this circle.
A(0,0)
We substitute this point to get;


B(-3,0)



But c=0


C(1,2)



Put the value of 'a' and 'c' to find 'b'




b=-2
Hence the center of the circle is

The answer is 77 but i don't see it as an option here ;/
