英语翻译
Using a sheet of paper and scissors,you can cut out two faces to form a cylinder in the following way:
Cut the paper horizontally (parallel to the shorter side) to get two rectangular parts.
From the first part,cut out a circle of maximum radius.The circle will form the bottom of the cylinder.
Roll the second part up in such a way that it has a perimeter of equal length with the circle's circumference,and attach one end of the roll to the circle.Note that the roll may have some overlapping parts in order to get the required length of the perimeter.
Given the dimensions of the sheet of paper,can you calculate the biggest possible volume of a cylinder which can be constructed using the procedure described above?

如果你使用一张纸和剪刀,你可以剪出两个面,由以下方式形成一个圆柱：
在与短边平行的方向水平裁剪,获得两个矩形.
从第一部分,剪出最大半径的圆,这个圆将被用于圆柱的底面.
把第二部分以某种方式卷起来——使它有一个和以上圆的周长相等的的周长,柱的一端连接到上面的圆.请注意,柱可能有一些重叠的部分,以获得周长所需的长度.
鉴于纸的尺寸,你可以计算出使用上述过程来构造一个圆柱体的最大容量?
（简而言之：一张矩形纸剪两个矩形,一个做圆柱的柱面,一个剪成圆形做底面,求最大容量下的裁剪策略.）hdoj..good luck.
