radius x^2+y^2-2x+8y-47=0

Lösung

radius

x^{2} + y^{2} - 2 x + 8 y - 47 = 0

Lösung

r = 8

Schritte zur Lösung

x^{2} + y^{2} - 2 x + 8 y - 47 = 0

Rewrite

x^{2} + y^{2} - 2 x + 8 y - 47 = 0

in the form of the standard circle equation

(x - 1)^{2} + (y - (- 4))^{2} = 8^{2}

Therefore the circle properties are:

(a, b) = (1, - 4), r = 8

And the radius is:

r = 8
