Perimeter of Semicircles #1

Assess your skill with semicircles in this seventh-grade worksheet! In each of these eight problems, students will need to apply their knowledge of circle circumference. The introduction provides a formula for students to use and an explanation that the perimeter of a semicircle is equal to half the circumference of the circle plus the length of the diameter. Learners can use this formula to solve each problem! 

This worksheet was designed to advance students’ understanding of circle geometry by challenging them to alter a formula they are already familiar with, then apply that formula to calculate perimeter. These problems can prepare students for real-world situations that involve semicircles and sectors.
