Beliebt Geometry >

radius 4x^2+4y^2-8y-5=0

Lösung

radius

4 x^{2} + 4 y^{2} - 8 y - 5 = 0

Lösung

r = \frac{3}{2}

Schritte zur Lösung

4 x^{2} + 4 y^{2} - 8 y - 5 = 0

Rewrite

4 x^{2} + 4 y^{2} - 8 y - 5 = 0

in the form of the standard circle equation

(x - 0)^{2} + (y - 1)^{2} = (\frac{3}{2})^{2}

Therefore the circle properties are:

(a, b) = (0, 1), r = \frac{3}{2}

And the radius is:

r = \frac{3}{2}
