Unit 6, Lesson 22# Area Problems with Circular Regions

EngageNY 45 min(s)

Students determine the area of composite figures and of missing regions using composition and decomposition of polygons. Students learned how to calculate the area of circles previously in Grade 7. Now that we know the radius, how can we find the area of the shaded region? Find the area of one quarter of the circle because the circle is divided into four identical parts, and only one part is shaded.
