you could always fill it with packing peanuts, then put them in a known square box and measure for volume

well the volume of a cyclinder is pi r^2 x length so

piX7.75^2x10.5

but idk if that would be consider correct due to the flares

hope it helps a little bit

Pi*r^2*h

Volume of the flares are negligable.

Gives you ~.29cuft.

^ Wrong, as you need the radius squared, not the diameter squared.
