Answer to Question #284950 in Python for eiss

Question

Malayan Yellow Hut’s Pizza parlor has specialized systems that can identify how many slices that can be taken from a pizza of a given size. This system uses 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 using the formula area = πr².

 

Improve their systems by allowing it to identify how many pizzas should be ordered given a number of people expected to eat and the diameter of the pizza. Assume that each person is expected to eat an average of 4 slices.

Input:

1. nOp

Description

no of person

2. dia

Description

diameter of pizza

Output:

Enter·the·number·of·person:·30

Enter·the·diameter·of·the·pizza:·12

You·should·order·15·pizzas·for·30·persons.

Answer 1

import math

No_of_Persons = int(input("Enter No. of Persons: "))

AvgDiet = 4    # Avg. Diet per person
SliceArea = 14.125
print("Unit Slice Area = ",SliceArea)
print("Avg. Diet per person = ",AvgDiet)

RequiredPizzaArea = No_of_Persons*SliceArea*AvgDiet
print("Required Pizza Area = ",RequiredPizzaArea," sq. inch")
PI = 3.157
R = math.sqrt(RequiredPizzaArea/PI)       # Radius of Pizza
D = round(2*R,2)
print("Required Diameter of Pizza = ",D," inches")
