Beliebt Geometry >

(x+2)^2+(y+1)^2=16

Lösung

(x + 2)^{2} + (y + 1)^{2} = 16

Lösung

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

Schritte zur Lösung

(x + 2)^{2} + (y + 1)^{2} = 16

Rewrite

(x + 2)^{2} + (y + 1)^{2} = 16

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

4 x^{2} + 4 y^{2} - 24 x + 16 y - 48 = 0

9 - x^{2} - y^{2} \geq 0

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

(x+3)^2+(y-5)^2=16

(x + 3)^{2} + (y - 5)^{2} = 16

a^{2} + b^{2} = 1
