y^2=-x^2+25

y^{2} = - x^{2} + 25

(a, b) = (0, 0), r = 5

Solution steps

y^{2} = - x^{2} + 25

Rewrite

y^{2} = - x^{2} + 25

in the form of the standard circle equation

(x - 0)^{2} + (y - 0)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (0, 0), r = 5

(x + 4)^{2} + y^{2} = 25

a^{2} + b^{2} = 2

x^{2} + y^{2} - 10 x - 4 y + 20 = 0

(x + 6)^{2} + (y - 7)^{2} = 36

2 x^{2} + 2 y^{2} = 50
