## Standards in this domain:

### Explain volume formulas and use them to solve problems

• HSG-GMD.A.1 Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. Use dissection arguments, Cavalieri’s principle, and informal limit arguments.
• HSG-GMD.A.2 (+) Give an informal argument using Cavalieri’s principle for the formulas for the volume of a sphere and other solid figures.
• HSG-GMD.A.3 Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems.

### Visualize relationships between two-dimensional and three-dimensional objects

• IA.7 Plot points in three-dimensions.
• HSG-GMD.A.4 Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.
