圆柱由两个底面和一个侧面组成,圆锥由一个底面和一个侧面组成.
The column consists of two base and one side, the cone is composed of a bottom surface and a side surface.
等底等高的圆柱和圆锥,圆锥体积等于圆柱体积的3分之1,圆柱体积等于圆锥体积的3倍.圆柱有两个底面,两底面平行且相等,都是圆形,侧面是个曲面,展开是个长方形.圆锥的侧面也是个曲面,展开是个扇形.
At the end of such high cylinder and cone, the volume of a cone is equal to 1 / 3 of the cylindrical volume, cylindrical volume equal to three times the volume of a cone. Cylinder and two bottom surface, two parallel to the bottom surface and equal, are circular, the side is curved, expansion is a rectangle. The side of the cone is a surface, unfolding is a fan.
圆柱有无数条高,圆锥只有一条高。
