radius x^2+y^2-12x-10y=-12

radius

x^{2} + y^{2} - 12 x - 10 y = - 12

r = 7

Solution steps

x^{2} + y^{2} - 12 x - 10 y = - 12

Rewrite

x^{2} + y^{2} - 12 x - 10 y = - 12

in the form of the standard circle equation

(x - 6)^{2} + (y - 5)^{2} = 7^{2}

Therefore the circle properties are:

(a, b) = (6, 5), r = 7

And the radius is:

r = 7

3 x^{2} + 3 y^{2} = 75

x^{2} - 4 x + y^{2} + 6 y = 24

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

x^{2} + y^{2} + 6 x - 4 y = 0

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