I guess user will fill the radius of the ball to the edit. You have to convert it from string to integer with r:=strtoint(Edit1.Text);
You can do it in event Button1.OnClick, together with the formulas above. And result write to the label, using Label1.Caption:=inttostr(Volume);
Just try yourself or show us what you already have.

It sounds like a homework.
Have you wrote something? Show us your code. If none, you should try to do it your best first then post your code here, so others can guide you.
