Perimeter of Quarter Circles #3

Confront questions with quarter circles in this seventh-grade geometry worksheet! Each of these eight problems asks students to find the perimeter of a quarter circle using only the radius. Learners can use the modified circumference formula given in the worksheet’s introduction to find a quarter of the circle’s circumference, then add twice the radius. 

Use this worksheet to challenge seventh-graders’ knowledge of circumference and perimeter. Learners will need to understand both concepts in order to apply the modified formula to the quarter circles. The ability to adapt existing formulas to fit their needs is a vital skill that can help students in real life and in math class!
