Nomer Ceniza Manalo, Feb 9, 2022

This book includes the objectives, prerequisites, and exclusions of the lesson, teaching students how to find the equation of a circle using its center and a given point or the radius and vice versa. At the end of this lesson, you must be able to: 1. find the center of a circle and its radius given its equation in standard form 2. construct a circle given the center, radius, and a point on the circle 3. write the equation of a circle in standard form/general form given its center and its radius, or a point on its circumference,
