3.18: Pizza Pi 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).

Respuesta :

Answer:

#program in python.

#variables

slice_area=14.125

pi=3.14159

#read diameter

d=int(input("Enter diameter of pizza:"))

#area of pizza

area=pi*(d/2)*(d/2)

#number of slice

no_slice=int(area/slice_area)

#print slice

print("total silce are:",no_slice)

Explanation:

Declare and initialize a variable "slice_area" with 14.125 which is the area of a pizza slice.Initialize a variable "pi" with 3.14159.Then read the diameter of pizza.Find the area of pizza as "area=pi *d/2*d/2".Divide the total area with area of pizza slice.This will be the number of slice.

Output:

Enter diameter of pizza:20                                                                                                

total silce are: 22
