Muffin Tin with Muffin (AR Modeling Challenge)

Topic:
Sphere
For this next GeoGebra Augmented Reality Modeling Challenge, the goal here is to recreate what you see in the screencast. Clues: Each circle (hole) shown has a radius of 1.5 units. The shortest distance between any 2 adjacent circles = 0.5 unit. The muffin top (part of a sphere) has its highest point located 1 unit above the pink plane. For a hint re: finding the radius of this sphere, you may want to take a look at this link.
