Doubled Spheres
Using the arrow tool, move the slider for a to manipulate this applet. The following are all based on the variable a:
-The radius of the small sphere is a
-The radius of the large sphere is 2a
-The volumes of the spheres are displayed dynamically on the left
-Point D is a point (x,y) of (radius, volume) for the small sphere
-Point E is a point (x,y) of (radius, volume) for the large sphere
