(x + 2)^2 + (y + 3)^2 = 9

Step-by-step explanation:

Center = (-2, - 3) = (h, k)

Radius (r) = 3

Equation of circle in centre radius form is given as:

$(x - h) ^2 + (y - k) ^2 = r^2 \\\therefore \{x - (-2)\}^2 + \{y - (-3)\}^2 = 3^2 \\ \purple {\boxed {\bold {\therefore(x + 2)^2 + (y + 3)^2 = 9}}}$
