Circles and Sectors
I.SectionObjectives
- Calculate the area of a circle.
- Calculate the area of a sector.
- Expand understanding of the limit concept.
II.Cross-curricular-History
- Use the following image from the round table used by King Arthur.
- This is Figure 10.05.01
- http://www.crystalinks.com/roundtable.gif
