Honors Geometry; 4/21

We continued our work with circles today by going over how to determine the area of a sector of a circle and also the length of an arc of the circle.  Both of these are linked to our earlier study of central angles, and each one considers a fraction of the total circle that is being asked about.  We went over 5-6 questions together that demonstrated how to go both forwards and backwards using the formulas.


Assignment:  section 11-6;  page 453;  CE  #1-6 (skip #5), WE #1-12
