Perimeter of Semicircles #2

Strengthen your skills with semicircles in this seventh-grade worksheet! Young mathematicians will be challenged to find the perimeter of eight semicircles given only the radius. They will need to use the formula provided by the worksheet’s introduction, which is a modified version of the circumference of a circle formula that accounts for the missing half of the circle and the length of the diameter, which is a side of the semicircle. 

This geometry worksheet was designed to test students’ knowledge of finding the perimeter of a shape and the circumference of a circle. These problems challenge students to apply a modified formula correctly, demonstrating that they understand the math concepts involved in both the original and modified formulas.
