Example 2 answers:
(AE)²+7²=9² (AE)²=9²-7² (AE)²= 32 (square root of 32) AE= 5.66 By the Radius and Chord theorem, AB bisects CD, so DE= CE=4. Therefore, CD=BE+DE= 5.66+5.66= 11.31(CD)

> 36 is the radius squared. To get the intercepts you use the radius (5). The center is 5 away from the intercept. (Created by Shelby)
 * 1) (x-4)²+(y+7)=36 -4 and +7 are the opposites of the center of the circle.
 * 1) x²+y²=25
