radius x^2+y^2+7x-2y-1=0

Lösung

radius

x^{2} + y^{2} + 7 x - 2 y - 1 = 0

Lösung

r = \frac{57}{2}

Schritte zur Lösung

x^{2} + y^{2} + 7 x - 2 y - 1 = 0

Rewrite

x^{2} + y^{2} + 7 x - 2 y - 1 = 0

in the form of the standard circle equation

(x - (- \frac{7}{2}))^{2} + (y - 1)^{2} = (\frac{57}{2})^{2}

Therefore the circle properties are:

(a, b) = (- \frac{7}{2}, 1), r = \frac{57}{2}

And the radius is:

r = \frac{57}{2}
