球的半径

思路

球的半径为球心到球上一点的距离，，球的体积为

#include<iostream>
#include<cmath>
#include <iomanip>

using namespace std;

int main(){
    int x0, y0, z0, x1, y1, z1;
    while(cin >> x0 >> y0 >> z0 >> x1 >> y1 >> z1){
        double r = sqrt((x1 - x0)*(x1 - x0) + (y1 - y0)*(y1 - y0) + (z1 - z0)*(z1 - z0));
        double v = 4/3.0*acos(-1)*pow(r, 3);
        cout << setprecision(3) << fixed << r << " " << v;
    }
    return 0;
}
