A solid lies between planes perpendicular to the x-axis at x = 0 and x = 12.

Question:

A solid lies between planes perpendicular to the x-axis at x = 0 and x = 12. The cross-sections by planes perpendicular to the x-axis are circular disks whose diameters run from the line y = x/2 to the line y = x as shown in the accompanying figure. Explain why the solid has the same volume as a right circular cone with base radius 3 and height 12.image
