【v4】a ** cylinder  be circumscribed by a square whose edge is 8 ,我当时犹豫了下，是圆柱体外切正方体，还是正方体外切 圆柱体，题目记得没错，大家讨论下吧，不过我还是选了8（根号2）。
-------------------------------------
根据字面翻译是圆柱被正方形切。。。。。

那是不是就是圆柱在正方形内的意思？如果是这种情况那直径就是8？

还是另一种意思？求解！谢谢了！

circumscribe: To enclose an object within a configuration of lines, curves, or surfaces so that every vertex of the enclosed object is incident on the enclosing configuration.

If a cylinder is circumscribed by a square, the cylinder is enclosed within the square.

So LZ is right.
