c# - 为什么阴影区域与矩形区域相同？

问题描述

这是我的第一篇文章，所以请多多包涵。我是 C# 的超级新手。我正在尝试以下操作：编写一个控制台应用程序，允许用户输入计算矩形面积、圆形面积所需的尺寸，然后显示下面阴影形状的面积。[1][1]：https://i.stack.imgur.com/u0kkN.png

这是我到目前为止所得到的：我的问题：它运行良好，虽然问题是当我运行程序时，唯一错误的是它计算的阴影区域值。它似乎将矩形的区域显示为阴影区域的答案。因此，如果我为矩形输入 10 个长度和 10 个宽度。阴影区域和面积一样将是 100。我在我的代码中看不到任何问题，我已经尝试了我能想到的一切。将不胜感激任何帮助。谢谢 <3
