Suppose that you work for a beverage company. The company wants to know the optimal cost for a cylindrical container that holds a specified volume. Write a fragment of code that uses an ask-before-iterating loop. During each iteration of the loop, your code will ask the user to enter the volume and the radius of the cylinder. Compute and display the height and cost of the container. Use the following formulas, where V is the volume, r is the radius, h is the height, and C is the cost.

Question

Answer 1

```
double volume = 0.0;
double height = 0.0;
double radius = 0.0;
double cost = 0.0;
String answer;

//Scanner reader = new Scanner(System.in);

do
{
System.out.println("Enter the volume and radius "
+ "of the cylinder ");
volume = reader.nextDouble();
radius = reader.nextDouble();

height = volume / (Math.PI * radius * radius);
cost = 2 * Math.PI * radius *(radius + height);

System.out.println("The height required is: "
+ height + " and the cost is " + cost);

System.out.println("Do you want to compute the "
+ "cost for a different volume & height?");
System.out.println("Enter yes or no.");
answer = reader.next();
} while (answer.equalsIgnoreCase("yes"));
```

This code is in Fragments.java.
