Lesson E: Circumference of Circles Objective: To use formulas to find the circumference of circles.

The circumference of a circle is the distance around the circle. Circumference:

Examples: Find the circumference of each circle below. Do not use an approximation. 1)2) 3) Use 22/7 as an approx. 4) Use 3.14 as an approx. 14 in 8 in Complete #4. Then complete #3. No calculator for #3!!

Multiply by the reciprocal! Try on your own first! Take about 5 minutes. Now get together with a group to try working through it if you had trouble. How do you move a fraction to the other side?
