Answer:Step-by-step explanation:Circle equation:

We need to find h, k , to complete the equation.

(h,k) is center point, in this case is given (-4,0) = (h,k)

h=-4

k=0

Substitute to equation:

Use the initial condition: circle passes through the point (-2,1) = (x,y)

x=-2

y=1

Substitute to equation:

Solve for = 5

Final answer:
