(8) Congruence and the geometry of size. The student uses tools to determine measurements of geometric figures and extends measurement concepts to find perimeter, area, and volume in problem situations. The student is expected to:

• (A) find areas of regular polygons, circles, and composite figures;

• (B) find areas of sectors and arc lengths of circles using proportional reasoning;

• (C) derive, extend, and use the Pythagorean Theorem;

• (D) find surface areas and volumes of prisms, pyramids, spheres, cones, cylinders, and composites of these figures in problem situations;

• (E) use area models to connect geometry to probability and statistics; and

• (F) use conversions between measurement systems to solve problems in real-world situations.
