Geometry; 5/31

Our study today focused on the volume and area of spheres.  We went over the two formulas that are involved with this shape, and also took a look at hemispheres as well.  The problems either started with the radius and then went towards volume and area, or they started with volume and went back to area or radius.  We worked on both types.
