    double fe = 7.86, au = 19.3, pi = 3.1415926;
    int d1, d2;
    double mfe, mau;
    scanf("%ld %ld", &d1, &d2);
    mfe = (4 / 3.0) * pi * ((double)d1 / 2.0) * ((double)d1 / 2.0) * ((double)d1 / 2.0) * (fe / 1000);
    mau = (4 / 3.0) * pi * ((double)d2 / 2.0) * ((double)d2 / 2.0) * ((double)d1 / 2.0) * (au / 1000);
    printf("%.3f %.3f", mfe, mau);
    return 0;

}
