we can find the volume of disk that way, 
reading the question again... looks like the question is asking us to setup integral for volume of big cone only

anonymous · Answer

just going to put this out there, the question asks for equation for the volume of a disk, the equation for the total volume of all disks (which will be an integral). does that help at all?
