In this circles learning exercise, high schoolers find the circumference of 20 circles.  Students find the circumference given the radius, diameter, and area of various circles.

Students identify the relationship between the radius and Pi. In this geometry lesson, students calculate the circumference and area of a circle. They create visuals to help them see how the circumference relates to Pi.

Students understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.

Formulas and procedures for finding the area and circumference are not provided on this handout, so it will be best used as a practice of already-acquired skills. It is a well-rounded assignment, however, as it includes diagrams,...
