(y+8)^2+(x+2)^2=72

(y + 8)^{2} + (x + 2)^{2} = 72

(a, b) = (- 2, - 8), r = 72

Solution steps

(y + 8)^{2} + (x + 2)^{2} = 72

Rewrite

(y + 8)^{2} + (x + 2)^{2} = 72

in the form of the standard circle equation

(x - (- 2))^{2} + (y - (- 8))^{2} = (72)^{2}

Therefore the circle properties are:

(a, b) = (- 2, - 8), r = 72

x^{2} + y^{2} = 9 x

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

x^{2} + y^{2} = 45

x^{2} + y^{2} = 41

x^{2} + y^{2} = 56
