radius x^2+y^2+4x+2y-11=0

Lösung

radius

x^{2} + y^{2} + 4 x + 2 y - 11 = 0

Lösung

r = 4

Schritte zur Lösung

x^{2} + y^{2} + 4 x + 2 y - 11 = 0

Rewrite

x^{2} + y^{2} + 4 x + 2 y - 11 = 0

in the form of the standard circle equation

(x - (- 2))^{2} + (y - (- 1))^{2} = 4^{2}

Therefore the circle properties are:

(a, b) = (- 2, - 1), r = 4

And the radius is:

r = 4
