The document discusses the equation of circles and provides examples of writing the equation given the center and radius. It includes the standard form of the equation of a circle (x - h)2 + (y - k)2 = r2 where (h, k) is the center and r is the radius. Students are given exercises to write the equation of circles based on given center points and radii. The document is from a math class and provides homework problems for students to practice writing equations of circles.
