radius x^2+y^2+14x-18y+49=0

Lösung

radius

x^{2} + y^{2} + 14 x - 18 y + 49 = 0

Lösung

r = 9

Schritte zur Lösung

x^{2} + y^{2} + 14 x - 18 y + 49 = 0

Rewrite

x^{2} + y^{2} + 14 x - 18 y + 49 = 0

in the form of the standard circle equation

(x - (- 7))^{2} + (y - 9)^{2} = 9^{2}

Therefore the circle properties are:

(a, b) = (- 7, 9), r = 9

And the radius is:

r = 9
