CLUE: A circle is the set of points equally distant from a specific point. The radius is the distance between any point on the circle and the center.

STRATEGY: Use the distance formula to find the value for the radius. Build the equation of your circle into the standard form equation for a circle.

KNOWLEDGE: Standard Form Equation for a circle is , and the center is (h,k); and the radius is r.
