612. The volume of the ball
Given your radius R of a sphere, please calculate the volume of the sphere.
The formula for calculating the sphere is V=(4/3)∗π∗R^3.
π takes 3.14159.
Note: 1.3333... is not available in some languages (4/3). It is recommended to use (4/3.0) in the formula.
Input format
Enter an integer R.
Output format
The output format is "VOLUME = X", where X is the volume of the sphere, and the result is to three decimal places.
data range
1≤R≤2000
Input sample:
3
Sample output:
VOLUME = 113.097
//C语言中 4/3要用 4/3.0 表示，分数不能用手写的那种格式
#include <cstdio>
int main()
{
int r;
double pi = 3.14159;
scanf("%d", &r);
printf("VOLUME = %.3lf", (4/3.0) * pi * r * r * r);
return 0;
}
