$1.$ This is a bit different from your earlier work as you are not writing a new program this time. Recall this program, which finds the volume of a cone given the radius and height as inputs, using the formula Volume $=1/3*$ PI $*$ radius squared $*$ height

$//$Cone Volume Calculator Program

$//$ Intro C$++$

$//$ Written by Bill H$,$ August $2023$

#include

using namespace std;

int main$()$

$\{$

$//$Declare variables and constants

$$double coneRadius $=0\mathrm{.}0$;

$$double coneHeight $=0\mathrm{.}0$;

$$const double PI $=3\mathrm{.}14$;

$$double coneVolume $=0\mathrm{.}0$;

$//$Prompt the user for inputs

$$cout $<<$ "Enter the radius of the cone: $"$;

$$cin $>>$ coneRadius;

$$cout $<<$ "Enter the height of the cone: $"$;

cin $>>$ coneHeight;

$//$Do the calculation

$$coneVolume $=0\mathrm{.}33*$ PI $*$ coneRadius $*$ coneRadius $*$ coneHeight;

$//$Display the result

$$cout $<<$ "The volume of your cone is: $"<<$ coneVolume $<<$ endl;

$$system$("$pause$")$;

$$return $0$;

$\}//$end of main

$2.$ For this assignment, we want the program to do the same thing, but with not one main$()$ function, but instead one main$()$ function PLUS one user defined function called computeConeVolume that contains the calculation. In other words, remove the one line calculation, replace it with a function call, then write and add the function below main with the calculation, surrounded any other syntax you need to complete it$.$ Determine how to do all that.

Notes:

$*$ The function should contain local variables and a constant declared and must have the calculation, it may not do anything else such as input or output.

$*$ You may not declare "global" variables anywhere. No variables above or outside of main$()$ and the function are allowed.

$*$ You may NOT use the same variable names for the cone parameters in main and in the function. They must be different, but still descriptive.

$*$ A value$-$returning function should be used because it's a little simpler to understand, but you can employ a void function if you desire.

$*$ Be sure to have a function prototype at the top of the code, then main, then your function.

$*$ Functions need comments just like all code does.

$*$ Think carefully about where you include universal constants $($like PI$),$ you include it only once in your program, but there is a "good" way to use it and a "bad" way, even though both ways can work. You are expected to use the "good" way.

$*$ You may test your code by entering and running the original program $($ with only main$()),$ then comparing the results to your new program.

$*$ Test with "real" numbers including decimals, like $3\mathrm{.}4$ and $5\mathrm{.}8$

$*$ Don't use $1$ anywhere $-$ that number is so simple it can give the right answer sometimes if the program is wrong.

$*$ Remember, a function that isn't called isn't used!
