Quick SIMPLE GEOMETRY LAB DUE TONIGHT by 10 pm

Materials:

• Five large round objects (larger objects work better) such as a paper plate, soup can, paper towel roll, bike wheel, clock, etc.

• Meterstick or metric sewing tape. If you do not have millimeters on your measuring device, please use this  printable ruler .

• Sewing thread or thin string to measure the circumference and diameter of each round object.

Project Steps:

1. With thread (or sewing tape if available), determine the amount of string needed to represent the circumference and diameter of each of your round objects.

2. Use a meterstick or tape measure to measure the string length for the circumference and diameter to the nearest millimeter (tenth of a centimeter).

3. Record your measurements in a table like the one that follows.

4. Calculate the ratio of the circumference to the diameter, C over D, and record the answers in your table.

5. Calculate the average of your C over D results.

Name of Object	Circumference ( C )	Diameter ( D )	C over D

1. What is the average value of your calculated C over D ratios?

2. What do you notice about the ratio of C over D?
