1 7.4A/7.4B STUDENT ACTIVITY #1 Write a formula that could be used to find the radius of a circle, r, given the circumference of the circle, C. The formula in the Grade 7 Mathematics Chart that relates the radius of a circle to its circumference is C =. Rewrite the formula so that it gives r in terms of C. To do so, divide both sides of the equation by. C 2 r C r The new formula C can be used to find the of a circle when given the of a circle. TEKSING TOWARD TAKS Weeks 3  Lesson 7 Page 1

Write the coordinates of the four points plotted on the graph. (, ), (, ), (, ), (, ) The xcoordinates of the points represent. The ycoordinates of the points represent. Fill in the table so that it shows the same relationship between the length of the diameter and the circumference of a circle.

3 7.4A/7.4B STUDENT ACTIVITY #3 WHERE DID COME FROM? Materials: Scissors, 1" grid paper, peelandstick dots, colored markers, clear tape, curling ribbon, rulers (customary), circular lids of various sizes (4 per group of 4 students) Procedure: Work in groups of 4. Identify Student #1, Student #2, Student #3 and Student #4. Student #1 measures and records the diameter of Lid #1 in the Lid Measurements Data Record. Student #2 measures and records the diameter of Lid #2 in the Lid Measurements Data Record. Student #3 measures and records the diameter of Lid #3 in the Lid Measurements Data Record. Student #4 measures and records the diameter of Lid #4 in the Lid Measurements Data Record. Student #1 uses curling ribbon to measure and represent the circumference of Lid #1. Wrap the ribbon around the lid, cut it, measure its length (in inches), and record its length in the Lid Measurements Data Record. (As an alternative method, make a mark on the edge of the lid, place this mark at the end of the ribbon, roll the lid for one complete revolution, mark the ribbon, cut it, measure its length (in inches), and record its length in the Lid Measurements Data Record.) Student #2 follows the same procedure to measure and represent the circumference of Lid #2. Student #3 follows the same procedure to measure and represent the circumference of Lid #3. Student #4 follows the same procedure to measure and represent the circumference of Lid #4. Student #1 gives the data from Lid #1 to the other students in the group so they can record on the Lid Measurements Data Record. Student #2 gives the data from Lid #2 to the other students in the group so they can record on the Lid Measurements Data Record. Student #3 gives the data from Lid #3 to the other students in the group so they can record on the Lid Measurements Data Record. Student #4 gives the data from Lid #4 to the other students in the group so they can record on the Lid Measurements Data Record.

4 Complete the table and answer the following questions: What do you observe about the ratio of C to d? What can you conclude from the table about the relationship between the circumference and diameter of a circle? Write an equation to represent the relationships between the circumference and diameter of a circle. Does this relationship hold true for all circles? Why or why not? Work together to graph the data from the table. Using the 1" grid paper, start the construction of a graph of the ordered pairs from the table (diameter, circumference) by placing Lid #1 with its diameter along the xaxis, one endpoint at the origin, and marking a point on the xaxis to correspond to the other end of the diameter. Take the ribbon corresponding to the circumference Lid #1 and tape one end of the ribbon at the endpoint of the diameter you just marked. Pull the ribbon up so that it forms a line segment parallel to the yaxis and secure the other end with a peelandstick dot. Repeat the process for Lid #2, Lid #3 and Lid #4 to make the graph on the 1" grid paper. Transfer the data from the table and the 1 grid paper to the grid below to make a graph. Title and label the graph. TEKSING TOWARD TAKS Weeks 3  Lesson 7 Page 4
5 After completing the graph answer the following questions: What does the length of the ribbon represent? What is the relationship between the ordered pairs on the graph and the data in the table? What appears to be true about the points represented by the peelandstick dots? Find the ratio of the length of the ribbon to the distance from the origin to the ribbon for each circle. Lid #1 Lid #2 Lid #3 Lid #4 Length of ribbon Distance from origin to ribbon length of ribbon dis tance from origin to ribbon Any Lid C d What does this ratio represent? Interpret the meaning of any ordered pair (d, C) on the graph using the ratio and the shape of the graph. Record your interpretation below. Use the graph to predict the diameter of a circle with a circumference of 24 inches. How did you determine your prediction? Use the graph to find the value of C in the ordered pair (9, C).
