$\backslash$pi can be computed using the following formula: $=4\backslash$times $(11/3+1/51/7+1/91/11+)$

Write a program that displays the result of $=4\backslash$times $(11/3+1/51/7+1/91/11)$

and

$=4\backslash$times $(11/3+1/51/7+1/91/11+1/13)$

$[$Hint: Use $1\mathrm{.}0$ instead of $1$ in the expression of your program. For example, if the math expression is

$=4\backslash$times $(11/3+1/5),$
