用c语言编写一个输入半径r1和半径r2求两个圆的周长和面积的代码

#include <stdio.h>
#define PI 3.1415926535

int main() {
    double r1, r2;
    printf("请输入圆1的半径：");
    scanf("%lf", &r1);
    printf("请输入圆2的半径：");
    scanf("%lf", &r2);

    double c1 = 2 * PI * r1;
    double s1 = PI * r1 * r1;
    double c2 = 2 * PI * r2;
    double s2 = PI * r2 * r2;

    printf("圆1周长：%.2f，面积：%.2f\n", c1, s1);
    printf("圆2周长：%.2f，面积：%.2f\n", c2, s2);
    printf("两圆周长之和：%.2f，面积之和：%.2f\n", c1 + c2, s1 + s2);

    return 0;
