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 π = 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
Since your program handles currency, make sure to use a data type that can store decimals.
Q1c)
A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk is $0.38, and the profit of each carton of milk is $0.27.
