Problem
Joe's Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should perform the following steps:
• Ask the user for the diameter of the pizza in inches.
• Calculate the number of slices that may be taken from a pizza of that size.
• Display a message telling the number of slices.
To calculate the number of slices that may be taken from the pizza, you must know the following facts:
• Each slice should have an area of 14.125 inches.
• To calculate the number of slices, simply divide the area of the pizza by 14.125.
• The area of the pizza is calculated with this formula: Area = "pi r squared" where pi is approximately 3.14159 and r is the radius (half the the diameter).
