x^2+y^2-25=0

x^{2} + y^{2} - 25 = 0

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

Solution steps

x^{2} + y^{2} - 25 = 0

Rewrite

x^{2} + y^{2} - 25 = 0

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

\frac{x ^{2}}{7} + \frac{y ^{2}}{16} = 1

\frac{x ^{2}}{16} + \frac{y ^{2}}{25} = 1

x^{2} - y^{2} = 14

\frac{x ^{2}}{4} + \frac{y ^{2}}{16} = 1

16 x^{2} + 192 x + 576 + 25 y^{2} = 1600
