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 n = 3.141593. 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: 0.017507
