Difference between 柱体 and 圆筒 I get the impression that 柱体 is more mathematical and 圆筒 is more about general &quot;drum shaped&quot; things. Are they interchangeable or is there a distinction?
柱体 is used more in geometry and engineering. It means a column-like body, which can be a square or rectangular column 方柱体, circular column 圓柱体, or any shape of columns.
筒 is a bucket. So 圓筒 is a round bucket or a barrel.
