First we identified the value of pi that we will be using...

**3.14**Be sure to type in 3.14 rather than using the pi key when you do your calculations. :)

**Circumference**is the distance around a circle, like the perimeter of a circle.

**Diameter**is the distance across a circle, through the center. Twice the length of the radius.

**Radius**is the distance from the center to the edge of a circle. Half the length of the diameter.

Tonight's homework is worksheet 4-7, all problems. Use the formulas from class and on the back of the sheet to help you solve the problems and remember to use 3.14 for pi and to use a calculator for your work!

Additional notes and information on circumference from Mr. Glosser's Math Goodies.

Explanation and game: KnowledgeBox Math Games (click on the kid to shoot! The longer you hold it the further is goes)

Information and an interactive circle that shows you how values change as a circle increases or decreases in size. From Math Warehouse.

(ignore the area part for now...)

Best of luck on the homework!
