where (h, k) is the _____________ and r is the __________
EXAMPLE:
1. What is the center and radius of the following circle? 2. Write the equation for the following circle.
Center = ____________
Radius = ___________
3. Given a radius of (-2, 12) and a radius of 11 write the equation of the circle.
Central Angle Notes
The measure of a central angle is ____________ the measure or the intercepted arc created by the angle.
The total number of degrees in a circle is _____________.
The total number of degrees in a semicircle is _________.
Together we will answer the following questions.
Use the picture below for the example questions. Tell whether each arc is a major arc, minor arc, or a semi-circle. Then, find the degree measure of each arc. BD is a diameter and CD is an angle bisector.
