Mathematics (2019) Grade(s): 09-12 - Geometry with Data Analysis

MA19.GDA.17

Model and solve problems using surface area and volume of solids, including composite solids and solids with portions removed.

Unpacked Content

Knowledge

Students know:
  • Techniques to find the area and perimeter of parallelograms,Techniques to find the area of circles or polygons

Skills

Students are able to:
  • Accurately decompose circles, spheres, cylinders, pyramids, and cones into other geometric shapes.
  • Explain and justify how the formulas for surface area, and volume of a sphere, cylinder, pyramid, and cone may be created from the use of other geometric shapes.

Understanding

Students understand that:
  • Geometric shapes may be decomposed into other shapes which may be useful in creating formulas.
  • Geometric shapes may be divided into an infinite number of smaller geometric shapes, and the combination of those shapes maintain the area and volume of the original shape.
