(x+19/2)^2+(y-2sqrt(30))^2=9

(x + \frac{19}{2})^{2} + (y - 230)^{2} = 9

(a, b) = (- \frac{19}{2}, 230), r = 3

Solution steps

(x + \frac{19}{2})^{2} + (y - 230)^{2} = 9

Rewrite

(x + \frac{19}{2})^{2} + (y - 230)^{2} = 9

in the form of the standard circle equation

(x - (- \frac{19}{2}))^{2} + (y - 230)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- \frac{19}{2}, 230), r = 3

(x + 1)^{2} + (y + 4)^{2} = 16

(x + 5)^{2} + y^{2} = 45

(x - 5)^{2} + (y - 5)^{2} = 25

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

x^{2} + y^{2} + 4 x - 8 y + 19 = 0
