Write a program that calculates the cost per square inch of a circular pizza, given its diameter and price (user input).

Create two functions(besides the main function):

One to compute the Area of the pizza

One to compute Cost per Square Inch

The main function calls the Area function, that function calls the Cost per Square Inch function, a value is returned to the Area function and that value is returned to the main function for printing (see below Pizza Flow diagram).

The formula for area is

Develop Test Data! What is the diameter of your pizza? What is the cost? With the diameter what is the area? With both area and cost what is the price per square inch?
