Written by Adi Ackerman, Head Teacher
A semicircle is half a circle and a quarter circle is one fourth of a circle, so their areas are half or a quarter of πr². There are 5 sheets for 8th grade here, each with an answer key and a worked example. Area of Semicircles and Quarter Circles finds areas, Perimeter of Semicircles and Quarter Circles adds the straight sides to the arc, and Semicircle Answers in Terms of Pi keeps every answer exact. Composite Figures With Semicircles and a lettered review round out the set.
