(x+6)^2+y^2=9

(x + 6)^{2} + y^{2} = 9

(a, b) = (- 6, 0), r = 3

Solution steps

(x + 6)^{2} + y^{2} = 9

Rewrite

(x + 6)^{2} + y^{2} = 9

in the form of the standard circle equation

(x - (- 6))^{2} + (y - 0)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- 6, 0), r = 3

x^{2} + y^{2} - 6 x - 2 y + 6 = 0

x^{2} + y^{2} = 425

x^{2} + y^{2} = 400

(x + 1)^{2} + (y + 2)^{2} = 8

x^{2} + y^{2} + 12 x + 18 y + 92 = 0
