Document Summary
A circle is the set of all points ( , The fixed distance r is called the radius of the circle and the fixed point ( , To derive the equation of a circle, we use the distance formula that was discussed in the previous section. A circle with center ( , )h k x y in the cartesian plane that are a fixed distance r from a fixed point ( , )h k is called the center of the circle. and radius r k r ( , )h k h. The standard form of an equation of a circle with center ( , )h k and radius r is ( x h. The standard form of an equation of a circle centered at the origin with radius r 2 x. Objective 1: writing the standard form of an equation of a circle.
