18y-15=-x^2-y^2

18 y - 15 = - x^{2} - y^{2}

(a, b) = (0, - 9), r = 46

Solution steps

18 y - 15 = - x^{2} - y^{2}

Rewrite

18 y - 15 = - x^{2} - y^{2}

in the form of the standard circle equation

(x - 0)^{2} + (y - (- 9))^{2} = (46)^{2}

Therefore the circle properties are:

(a, b) = (0, - 9), r = 46

x^{2} + y^{2} + 2 x - 10 y - 2 = 0

(x - 1)^{2} + \frac{( y - 3 ) ^{2}}{1} = 4

(x - 4)^{2} + (y + 3)^{2} = 5

x^{2} + z^{2} = 36

(x + 1.6)^{2} + (y + 9.8)^{2} = 26
