Question

If the center of the circle is (2,-2) and the radius is square root of 6 what is the equation of the cirlce in standard form?

Answer 1

The general form for the equation of a circle can be written as
\[ (x-h)^2+(y-k)^2 = r^2 \] where (h,k) is the center of the circle and r is the circle's radius. Try applying the information you've been given to this formula and see what you get!
