计算半球体积和表面积的程序-yiteyi-C++库

计算半球的体积和表面积。 半球： 在几何学中，它是球体的精确一半。我们可以找到许多现实生活中半球的例子，比如我们的地球可以分为两个半球——南半球和北半球。

null

半球体积： 半球的体积就是半球所占据的空间量。它也被定义为由半球边界包围的三维空间的数量。 表面积： 正好覆盖半球表面的正方形单位数。 表面积= $2 pi r^2$ 体积= $frac{2 pi r^2}{3}$ 例如：

Input :  Radius = 7Output : Volume = 718.378         Surface Area = 307.876Input :  Radius = 11Output : Volume = 2787.64         Surface Area = 760.265
