Sometimes old-fashioned practice is exactly what your students need.
Using a chart format to represent radius, diameter, area, and circumference will allow students to recognize patterns when the area and circumference of a circle are left in terms of pi.
Two worksheets (20 questions each) are included in this download. The second worksheet is slightly more challenging than the first. Check out the preview for a better idea of the format.
Objective: Students will determine measures related to circles in terms of pi.
