Have students measure the circumference, diameter, and radius in millimeters. Fill in each of the three measurements and then use a calculator to compare the indicated measurements. Provide students with a collection of four or five circular objects (e.g., lid, flying disc, roll of tape, etc.), a piece of string, and a ruler. Ask students to ...

Students also understand the ratio of circumference to diameter can be expressed as pi. Building on these understandings, students generate the formula for circumference and area. The illustration shows the relationship between the circumference and area. If a circle is cut into wedges and laid out as shown, a parallelogram results.

Set up the axes fo r the graph of circumference and diameter in your notebook. As you compute each pair of average values, plot them on the graph. (Note that for the preliminary graph, you n eed not calculate the average value. You can estimate the average value of the set of numbers. After collecting all of your data, you can then resort to a ...

This lesson would teach circumference by having students involved in measuring diameter and circumference of various sized circles. Students will build a chart of their measurements and look for the relationship between diameter and circumference. Students will then use the circumference formula to solve problems with one missing variable.

We can use this to estimate the circumference if we know the diameter, and vice versa. For example, using 3.1 as an approximation for π , if a circle has a diameter of 4 cm, then the circumference is about (3.1)⋅4=12.4 or 12.4 cm.

The diameter is the longest distance from one end of a circle to the other. is the ratio of the circumference of a circle to its diameter. For any circle, if you divide its circumference by its diameter, you get a value close to. This value is approximately 3.14159265358979323846... We use the Greek letter (Pi) to represent this value. ...
