Volume of a cone worksheets
A cone holds exactly a third of the cylinder it fits inside. These free printable worksheets give one measurement and the height, with answers that divide cleanly.
If they get stuck
Volume of a cone
The answer key prints on a separate page.
What's on this sheet
The third is the whole difference from the cylinder, and it is worth showing rather than stating: a cone poured into a cylinder of the same base and height fills it in exactly three goes. A child who has seen that does not forget which way the fraction goes.
Why this sheet works
The radius-or-diameter decision matters here for the same reason it does on a cylinder, and slightly more — there is now a third to keep track of as well. Each figure names its measurement, and a sheet can be set to one kind or left mixed.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
