Question

2.1 Area of a Pizza Pie Pizzas in the USA are just big circles of bread, cheese, and tomato sauce, mea- sured by the size of their diameter in inches. You can use that to get the area of the circle, which is measured in square inches. Write a method which takes in the diameter of a circle and returns the area. Remember: d=2r a=π 2.2 Computing the Price per Square Inch Figuring out the price per square inch should be its own method. Given the area of a circle in square inches and the price, the method should return the price per square inch. 2.3 Interactivity Your program should be interactive. This means that the program should ask the user to enter the size of the pizza and the price.4 All the input from console and output to the user should happen on in main

Need help with this problem by using JAVA and in second picture I have circled the Extra Credit, if possible. Please help and Thank you so much in advance.!

Answer 1

import java.util.Scanner;

public class Pizza{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter the number of pizzas: ");

int noOfPizzas = in.nextInt();

double cost, cheapestPizza = 99999;

while(noOfPizzas > 0){

System.out.print("\nEnter the size of pizza: ");

double size = in.nextDouble();

System.out.print("Enter the price of pizza: ");

double price = in.nextDouble();

cost = getCost(size, price);

if(cost < cheapestPizza)

cheapestPizza = cost;

noOfPizzas--;

}

System.out.println("The cheapest pizza is $" + cheapestPizza);

}

private static double getCost(double size, double price) {

return size * price;

}

}

Enter the number of pizzas: 3 Enter the size of pizza: 5 Enter the price of pizza: 10 Enter the size of pizza: 7 Enter the price of pizza: 6 Enter the size of pizza: 5 The cheapest pizza is $25.0 Enter the price of pizza: 5
