Chapter 4, Problem 14E

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.

   $\begin{array}{l}h=\frac{V}{\pi r^2}\\ C=2\pi r(r+h)\end{array}$
