(The conical paper cup problem) You have been given the contract for making little conical cups that come with bottled water.
These cups are to be made from a circular waxed paper of 4 inches in radius by removing a sector of length x (see Figure 5-4 below). By closing the remaining part of the circle, a conical cup is made.
Your objective is to remove the sector so that the cup is of maximum volume.
Instructions
Write a program that prompts the user to enter the radius of the circular waxed paper.
The program should then output:
- The length of the removed sector so that the resulting cup is of maximum volume
- The maximum volume
Calculate your answer to two decimal places.
Use 3.141592654 for PI
Format your output with setprecision(2) to ensure the proper number of decimals for testing!
