Math Project – Exploring the Circumference and the area of a circle
(Remember Area is all about the radius!!... Circumference is all about the Diameter!)
Part 1 – Circle Vocabulary
1. Draw a circle. Label the radius, diameter, circumference, centre, a chord and an arc.
Part 2 – Finding the circumference (think diameter!)
2. What is the formula to calculate the Circumference of a circle?
3. Describe in words how this formula works.
4. Explain (in words) how we compared the diameter and circumference using yarn.
5. Display your Excel Circumference database.
6. Discuss how your results compare to other groups in the class.
Part 3 – Finding the Area (think radius!)
7. What is the formula to calculate the area of a circle?
8. Describe in words how the formula works.
9. Choose three methods to calculate the area of a circle. Describe and demonstrate each method.
10. Which method was most accurate? Explain.
Part 4 – Pi
11. What is pi? Explain in your own words. List your sources of information.
BONUS
12. Demonstrate more than three ways to find the area.
13. Include more information about pi (history, other uses for it…)
14. Produce creative art inspired by circles or pi (Anything goes – painting, anime, video, song, spoken word. Have fun! )
Presentation: You can choose the format: duotang, poster, video or other.
Due date: Wednesday November 3rd , 2010. Some work will be done in class, but you will need to work at home too.
See me outside of class time if you would like to work with a partner.
