Question 117445
{{{(x-3)^2 +(y-1)^2 =36}}}
That conic section is a circle centered at (3,1) with a radius of 6. 
It's graphed here with some missing sections at the edges. 
{{{ graph( 300, 300, -5, 10, -5, 10, 1+sqrt(36-(x-3)^2),1-sqrt(36-(x-3)^2)) ) }}} 
The general formula for a circle centered at (h,k) wih a radius R is,
{{{(x-h)^2 +(y-k)^2 =R^2}}}
