We introduced the final solid object that we will be studying today by going over spheres. We took a look at how to find both the volume and surface area of spheres. We also saw how the calculations look different with hemispheres. There are several different applications of spheres that we took a look at, and specifically calculated the circles of intersection when planes intersect spheres.
