Question 12
Hasan cuts his hollow conical hat horizontally at half its height, turns the upper part upside down and inserts it into the lower part, as shown. The original cone has radius 2 and height 8. What volume does the resulting shape enclose?
Model note: “Volume” means the enclosed capacity of the folded hollow shape, as in the source, rather than the material volume of the hat.
