Area of Semicircles #1

Use your knowledge of circle geometry to find the area of semicircles in this helpful worksheet! Students will be shown eight problems that each contain a semicircle with a given radius. The area of a semicircle is half the area of a circle, so students can solve the problems by using πr²—the formula for finding the area of a circle—then dividing by two. 

This worksheet is perfect for seventh graders learning about geometry and geometric formulas. Learners can not only practice finding the area of a circle, but also apply that skill to finding the area of a different shape. These problems prepare students to find the area of circular and semicircular objects in real life and in their continued math education.
