radius x^2+y^2-8x+18y+16=0

Lösung

radius

x^{2} + y^{2} - 8 x + 18 y + 16 = 0

Lösung

r = 9

Schritte zur Lösung

x^{2} + y^{2} - 8 x + 18 y + 16 = 0

Rewrite

x^{2} + y^{2} - 8 x + 18 y + 16 = 0

in the form of the standard circle equation

(x - 4)^{2} + (y - (- 9))^{2} = 9^{2}

Therefore the circle properties are:

(a, b) = (4, - 9), r = 9

And the radius is:

r = 9
