圆柱的侧面积公式

圆柱的侧面积公式圆柱是一种三维几何体，它由一个圆形的底面和与底面平行的侧面组成。圆柱的侧面积是指剥去底面，仅保留侧面的表面积。

要推导圆柱的侧面积公式，我们首先需要了解圆柱的性质和相关几何概念。

圆柱的底面是一个圆，具有半径r，面积S1=πr²，其中π是一个常数，约等于3.14159。

圆柱的侧面是一个矩形，它的高度为h，底边长为圆的周长2πr。

为了推导圆柱的侧面积公式，我们可以将侧面展开成一个长方形，该长方形的长边等于圆柱的高度h，短边等于圆的周长2πr。

根据长方形的面积公式S2=长x宽，侧面积S2=2πrh。

综上所述，圆柱的侧面积公式为S=2πrh。
