cout $$ fixed $$ setprecision $(2)$ myFloat;

Now, implement this syntax and output area and circumference with three digits after the decimal point, respectively. You may write your code $(2$ lines, one line for area and one line for circumference$)$ right after printing out area and circumferences. $($see $/*$ Write your code here! Write your code here! $*/$

return $$;

$\}$

Now with input $3$ and only keeping $3$ digits after decimal point, what is the area and circumference, respectively? $($provide the exact output value with correct precision you get from the run$)$
