下面是一个简单的C语言程序,它定义了一个名为calculateArea的函数,用于计算并返回圆的面积: ```c#include#define PI 3.1415926double calculateArea(double radius) {return PI * radius * radius;}int main() {double radius = 5.0;double area = calculateArea(radius);printf("The area of the circle is %...
The area of a circle with a radius of 5 cm is ___. A. 25π cm² B. 10π cm² C. 5π cm² D. 75π cm² 相关知识点: 试题来源: 解析 A。本题考查圆的面积计算公式,圆的面积 = π×半径²。半径为 5cm,所以面积为 25π cm²。选项 B 计算错误,应为 25π cm...
