Youll need to complete the square to do this. Example 2: Write the equation in standard form then find the center and the radius. 26 44 10 6 2 2 = +-+ + y x y x Example 3: Write the equation in standard form then find the center and the radius. 20 10 20 5 5 2 2 = + + +-+ + + y x y x We can also write the equation of a circle, given appropriate information. Example 4: Write the equation of the circle with center (-5, 2) and has radius 5 3 . Section 8.2a - Circles 3 Example 5: Write an equation of a circle with center (1, 3) which passes through the point (4, -7). Example 6: Write an equation of a circle if the endpoints of the diameter of the circle are (6, -3) and (-4, 7)....
