I am creating a code for my class:

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 11.15 inches square.

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

Once I insert the diameter from `std::cin`

, do I then calculate the Area of the pizza & divide that by the Area of slices?
