radius (x+2)^2+y^2=9

Lösung

radius

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

Lösung

r = 3

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - (- 2))^{2} + (y - 0)^{2} = 3^{2}

Therefore the circle properties are:

(a, b) = (- 2, 0), r = 3

And the radius is:

r = 3
