Front

What is the standard form of a circle's equation?

Back

The standard form of a circle's equation is (x-h)² + (y-k)² = r², where (h,k) is the center and r is the radius.

Front

How do you identify the center and radius from the equation of a circle?

Back

From the equation (x-h)² + (y-k)² = r², the center is (h,k) and the radius is r.
