c$++$ Instructions

Write a program to implement and test the algorithm that you designed for Exercise $15$ of Chapter $1.$ The instructions to Exercise $15$ have been posted below for your convenience:

Exercise $15$

Given the radius, in inches, and price of a pizza, design an algorithm to find the price of the pizza per square inch.

You may assume that the value of $\backslash$pi $=3\mathrm{.}141593.$

In your program, declare a named constant PI to store this value.

Below is an example of how the completed program should work:

Enter the radius of the pizza: $20$

Enter the price of the pizza: $22$

The price per square inch is: $0\mathrm{.}017507$

Since your program handles currency, make sure to use a data type that can store decimals.

Task #$01$: Declare PI as a constant

Test Feedback:

No attempts made

Task #$02$: Correct output calculated and displayed

Test Feedback:

Status: FAILED!

Check: $1$

Test: Test case $1$

Reason: Unable to find $\text{'}[\text{'}0\mathrm{.}037\text{'}]\text{'}$ in the program's output.

Enter the radius of the pizza: Enter the price of the pizza: $Price of the pizza per square inch: $$0\mathrm{.}0373019$

$.$

Error : AssertionError $-$ Unable to find $0\mathrm{.}037$ in the program's output.
