Exercise 2: Write a program that calculates the cost per square inch of a circular pizza, given its diameter and price. The formula for area is A = r2
Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:
import java.util.*;
import java.text.*;
public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
DecimalFormat df = new DecimalFormat("#.##");
System.out.println("Enter diameter of pizza: ");
double diameter = scan.nextDouble();
System.out.println("Enter price of pizza: ");
double price = scan.nextDouble();
double area = Math.PI * Math.pow(diameter/2, 2);
System.out.println("The price of pizza per square inch is " + df.format(price/area) + " per square inch");
}
}
