radius 2x^2+2y^2+28x-8y+4=0

Lösung

radius

2 x^{2} + 2 y^{2} + 28 x - 8 y + 4 = 0

Lösung

r = 51

Schritte zur Lösung

2 x^{2} + 2 y^{2} + 28 x - 8 y + 4 = 0

Rewrite

2 x^{2} + 2 y^{2} + 28 x - 8 y + 4 = 0

in the form of the standard circle equation

(x - (- 7))^{2} + (y - 2)^{2} = (51)^{2}

Therefore the circle properties are:

(a, b) = (- 7, 2), r = 51

And the radius is:

r = 51
