Understanding a piece of code

[Michael1]

def area(x,y = 3.14): # formal parameters
    a = y*x*x
    print (a)
    return a

a = area(10)
print("area",a)

* Here is what I am doing:
3.14 * 3.14 * 3.14 = 30.56476
30.56476 is a
then 30.56476 * 10
305.6476

but the actual answer is: 314.0 ( when you run the program)
