Question

Dairy Farm decided to ship milk in containers in the form of cubes rather than cylinders. Write a program called ws4.cpp that prompts the user to input the radius of the base and the height of a cylindrical container and outputs the side of the cube with the same volume as the cylindrical container.

Answer 1

Answer:

1. #include <iostream>

2. #include <cmath>

3.  

4. using namespace std;

5.  

6. int main()

7. {

8.     float radius;  

9.     cout << "Type the radius of the base: "; // Type a number

10.     cin >> radius ; // Get user input from the keyboard

11.      

12.     float height;  

13.     cout << "Type the height: "; // Type a number and press enter

14.     cin >> height; // Get user input from the keyboard

15.      

16.     float volumeCylinder = 3.1416 * radius * radius * height;

17.     float cubeSide = std::pow(volumeCylinder, 1/3.);

18.     cout<<"Cube side is: "<< cubeSide;

19.      

20.     return cubeSide;

21. }

Explanation:

• From line 1 to 5 we include two libraries
• From line 6 to 7 we declare our main function
• From line 8 to 11 we ask the user for the radius of the cylinder
• From line 12 to 15 we ask the user for the height of the cylinder
• On line 16 we calculate the volume of the cylinder using the formula        V=pi*(r^2)*h
• On line 17 we calculate the side of the cube with the same volume as the cylindrical container using the formula side=∛(V)
• From line 18 to 21 we print and return the value of the cube's side
