Question

Consider the following program in which the statements are in the incorrect order. Rearrange the statements so that the program prompts the user to input the height and the radius of the base of a cylinder and outputs the volume and surface area of the cylinder. Formant the output to two decimal places.

#include <iomanip>
#include <cmath>

int main ()
{}

double height;

cout << ”Volume of the cylinder = “
<<PI * pow(radius, 2.0) * height << endl;

cout << “Enter the height if the cylinder: “;
cin >> radius;
cout << endl;

return 0;

double radius;

cout << “Surface area: “
<< 2 * radius * + 2 * PI * pow (radius, 2.0) << endl;
cout << fixed << showpoint << setprecision (2);

cout << “Enter the radius of the base of the cylinder: “;
cin >> height;
cout << endl;

#include <iostream>
const double PI = 3.14159;

using namespace std;

Answer 1

The correct order of the code is as follows:

Program screenshot:

#include <iostream> #include <iomanip> #include <cmath> using namespace std; int main() const double PI = 3.14159; double height; double radius; cout << "Enter the height if the cylinder: "; cin >> height; cout << endl; cout << "Enter the radius of the base of the cylinder: "; cin >> radius; cout << endl; cout << fixed << showpoint « setprecision (2); cout << "Volume of the cylinder = ". <<PI * pow(radius, 2.0) * height << endl; cout << "Surface area: " «< 2 * radius * + 2 * PI * pow (radius, 2.0) << endl; return 0;

Sample output:

Enter the height if the cylinder: 6 Enter the radius of the base of the cylinder: 2 Volume of the cylinder = 75.40 Surface area: 100.53

Code to copy:

#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;

int main ()
{
const double PI = 3.14159;
double height;
double radius;

cout << "Enter the height if the cylinder: ";
cin >> height;
cout << endl;
cout << "Enter the radius of the base of the cylinder: ";
cin >> radius;
cout << endl;
cout << fixed << showpoint << setprecision (2);
cout << "Volume of the cylinder = "
<<PI * pow(radius, 2.0) * height << endl;

cout << "Surface area: "
<< 2 * radius * + 2 * PI * pow (radius, 2.0) << endl;
return 0;
}
