(x+55)^2+(y-11.5)^2=121

(x + 55)^{2} + (y - 11.5)^{2} = 121

(a, b) = (- 55, 11.5), r = 11

Solution steps

(x + 55)^{2} + (y - 11.5)^{2} = 121

Rewrite

(x + 55)^{2} + (y - 11.5)^{2} = 121

in the form of the standard circle equation

(x - (- 55))^{2} + (y - 11.5)^{2} = 1 1^{2}

Therefore the circle properties are:

(a, b) = (- 55, 11.5), r = 11

(x - 3)^{2} + (y - 4)^{2} = 36

4 x^{2} - 4 x + 4 y^{2} + 24 y + 21 = 0

x^{2} + y^{2} - 2 x - 2 y - 18 = 0

(x - 5)^{2} + (y + 7)^{2} = 50

x^{2} + (y + 8)^{2} = 36
