radius 4x^2+4y^2-4x+12y-6=0

radius

r = 2

Solution steps

4 x^{2} + 4 y^{2} - 4 x + 12 y - 6 = 0

Rewrite

4 x^{2} + 4 y^{2} - 4 x + 12 y - 6 = 0

in the form of the standard circle equation

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

Therefore the circle properties are:

(a, b) = (\frac{1}{2}, - \frac{3}{2}), r = 2

And the radius is:

r = 2
