Question 838274
No, because they wouldn't be equivalent.
{{{(x-6)^2+(y-6)^2=sqrt(164)}}}
{{{x^2-12x+36+y^2-12y+36=sqrt(164)}}}
{{{x^2+y^2-12x-12y=sqrt(164)-72}}}
Clearly those two equations are not identical.

{{{6x^2+6y^2=162}}}
Divide by {{{6}}}
{{{x^2+y^2=27}}}
Complete the square in x and y.
{{{(x-0)^2+(y-0)^2=27}}}
{{{h=0}}}
{{{k=0}}}
{{{R=sqrt(27)=3sqrt(3)}}}
