❔ How do I make it to show only 5 digits after comma?

double R = 2.4;
double pi = 3.1415926;
int C = 2;
int D = 4;
double E = 3;
Console.WriteLine("Rādiuss R = " + R);
Console.WriteLine("Riņķa Līnijas Garums = "+ C* pi *R);
Console.WriteLine("Riņķa Laukums = " + pi * R*R);
Console.WriteLine("Lodes laukums = " + D * pi * R*R);
Console.WriteLine("Lodes Tilpums= " + Math.Round (D * pi * R *R*R) / E);
