Morphology
The meaning 'a cone with the top cut off' follows directly from combining 'truncated' (cut or removed) with 'cone' (a shape narrowing to a point), so the overall concept is literally compositional. This is a straightforward geometric construction that is cross-linguistically common, so a B1 learner who knows both constituents will readily infer the MWE's meaning.
Etymology
Truncated cone comes from the simple image of a cone with its point cut off. The word truncated means 'cut off', so the shape keeps a wide circular base and a smaller top and looks like a cone with the 'tip' removed, which is why we call funnels and some lampshades a truncated cone.
