The diameter of a robot wheel is about 6.7 cm which makes the circumference of the wheel approximately 21 cm. The wheels need about 4.76 revolutions forward for the robot to travel 100 cm. Question number seven is intended to lead students to the equation: circumference equals pi times diameter (C = d).

2. Students will use a ruler to measure the length of the diameter of each circle, and use a ruler and string to measure the circumference of each circle. Students will use the List function on the TI-83 plus to record data in . small groups. Students will then create a new "Ratio" list by dividing the circumference list by the diameter list. 5.
