I defined variables and make it output circle area

I did it indivudally but will check with groups when we find time to meet.
1 value is like valid things that stand for specific things, like Pi, like ture or false
 name does not represent the same things all the time. It might differ with time, culture, or how you define things
 variable is useful in programming as it allow people to freely define things and program based on their own needs
 Value is fixed and can only solve specific problems (like 5*2 = 10) while name is more flexible, it allows
 me to change different number later (like circle area).
