圆柱(cypnder)是一种图形，是由一个圆的底面和与底面相平的两个平面所围成的立体图形。它的英文来源是希腊语 "kypndros"，意思是"圆柱体"。

圆锥(cone)是一种图形，是由一个圆的底面和一条连接圆心和底面的尖顶所围成的立体图形。它的英文来源是希腊语 "konos"，意思是"圆锥体"。

下面是一些关于圆柱和圆锥的英文例句及其中文翻译：

The cypnder has a radius of 2 cm and a height of 10 cm. (圆柱的半径是2厘米，高度是10厘米。)
The cone has a radius of 3 cm and a height of 15 cm. (圆锥的半径是3厘米，高度是15厘米。)
The volume of the cypnder is calculated by multiplying the base area by the height. (圆柱的体积是通过乘上底面积和高度来计算的。)
The volume of the cone is calculated by multiplying the base area by the height and dividing by 3. (圆锥的体积是通过乘上底面积和高度并除以3来计算的。)
