Hi, there--
.
The form for the equation for a circle in standard form is
.

.
where
(h,k)=(0,0) is the center of the circle and r = sqrt(13) is the radius.
.
Substitute your values for the center and radius of the circle into the equation.

.
Simplify.

.
That's it. Feel free to email me via gmail if the explanation is unclear.
