Beliebt Geometry >

x^2-8x+16+y^2-18y+81=16

Lösung

x^{2} - 8 x + 16 + y^{2} - 18 y + 81 = 16

Lösung

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

Schritte zur Lösung

x^{2} - 8 x + 16 + y^{2} - 18 y + 81 = 16

Rewrite

x^{2} - 8 x + 16 + y^{2} - 18 y + 81 = 16

in the form of the standard circle equation

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

Therefore the circle properties are:

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