Problems Plus 6: Largest Sphere in a Sphere

In this video I find the largest sphere that passes through a given point while every point inside is also inside a larger sphere. Although the problem states every point inside the sphere satisfies an inequality, simply completing the squares multiple times reveals that the inequality is just in the form of a large sphere. Using the radius of the larger sphere, its center, and a unit vector from our point to the center of the big sphere, we can obtain the formula for our inside sphere. I also graph our spheres with the amazing GeoGebra 3D graphing calculator: https://www.geogebra.org/3d/dtdpukqs
