Question

x² + y² + 6x = 0 ajudem por favor

Answer 1

Bom dia Beto!


Solução!


$x^{2} +y^{2}+6x=0\\\\\\ Veja ~~que~~ n\~ao~~tem ~~o~~ termo~~ y~~ depois~~ do ~~6x,ent\~ao ~~y=0\\\\\\\ -2x=6\\\\\ x= \dfrac{6}{2}\\\\\ x=-3\\\\\\\ \boxed{Centro(-3,0)}$



$Raio= \sqrt{ x^{2} +y^{2} }\\\\\\ Raio= \sqrt{ (-3)^{2} +(0)^{2} }\\\\\\ Raio= \sqrt{ 9+0 }\\\\\\ Raio= \sqrt{ 9 }\\\\\\ \boxed{Raio=3}$

Bom dia!
Bons estudos!
