Calculate Sphere - Circumference, Surface, Volume

int main() {
    double radius;
    printf("Enter radius value: ");
    scanf("%lf", &radius);

    double circumference = 2 * M_PI * radius;
    double surface = 2 * circumference * radius;
    double volume = surface * radius / 3;

    printf("circumference: %lf\nsurface: %lf\nvolume: %lf\n",
           perimeter, surface, volume);

    return 0;
