John has been printing solid cones but would like to be able to produce more cones per each length of filament than you calculated in problem 7. without changing the outside dimensions of his cones, what is one way that he could make a length of filament last longer? sketch a diagram of your idea, and determine how much filament john would save per piece. then, determine how many cones john could produce from a single length of filament based on your design.
