Lamar is using a 3D printer to construct a circular cone that has a base with radius 6 in.

If his 3D printer prints in layers that are 0.004 in. thick (similar to what is shown in the image below), what should be the change in radius for each layer in order to construct a cone with height 4 in.?

What is the area of the base of the 27th layer?
