radius x^2+y^2-7x=15-2y

radius

x^{2} + y^{2} - 7 x = 15 - 2 y

r = \frac{113}{2}

Solution steps

x^{2} + y^{2} - 7 x = 15 - 2 y

Rewrite

x^{2} + y^{2} - 7 x = 15 - 2 y

in the form of the standard circle equation

(x - \frac{7}{2})^{2} + (y - (- 1))^{2} = (\frac{113}{2})^{2}

Therefore the circle properties are:

(a, b) = (\frac{7}{2}, - 1), r = \frac{113}{2}

And the radius is:

r = \frac{113}{2}

(x - 3)^{2} + (y + 5)^{2} = 25

x^{2} + (y + 4)^{2} = 121

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

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

(x + 2)^{2} + (y - 3)^{2} = 9
