如何使用 C 编程语言计算球体的体积?
球体的体积只不过是形状的容量。
球体的体积公式如下 −
$$V\:=\:\frac{4}{3}\Pi\:r^{3}$$
算法
Step 1: Enter radius of sphere at runtime Step 2: Apply the formula to variable Volume=(4/3)*3.14*rad*rad*rad Step 3: print the volume Step 4: stop
程序 1
#include<stdio.h> int main(){ float vol; int rad; rad=20; vol=((4.0f/3.0f) * (3.1415) * rad * rad * rad); printf("the volume of a sphere is %f
",vol); return 0; }
输出
the volume of a sphere is 33509.335938
程序 2
以下是计算球体体积与表面积的一个示例 −
#include <stdio.h> #include <math.h> int main(){ float rad; float area, vol; printf("Enter radius of the sphere :
"); scanf("%f", &rad); area = 4 * (22/7) * rad * rad; vol = (4.0/3) * (22/7) * rad * rad * rad; printf("Surface area of sphere is: %.3f", area); printf("
Volume of sphere is : %.3f", vol); return 0; }
输出
Enter radius of the sphere : 4 Surface area of sphere is: 192.000 Volume of sphere is : 256.000
