Question

C++ CODE

Answer 1

Answer:

#include <iostream>

#include <cmath>

#include <iomanip>

using namespace std;

int main()

{

   const double PI = 3.14159;

   double height;

   double radius;

   

   cout << "Enter the height of the cylinder: ";

   cin >> height;

   cout << "Enter the radius of the base of the cylinder: ";

   cin >> radius;

   cout << endl;

   cout << "Volume of the cylinder = " << setprecision(4) << PI * pow(radius, 2.0) * height << endl;

   cout << "Surface area: " << setprecision(4) << 2 * PI * radius * height + 2 * PI * pow(radius, 2.0) << endl;

   cout << endl;

   return 0;

}

Explanation:

Code is rearranged so that;

- Variables are defined,

- height and radius of the cylinder is asked from the user,

- The volume and surface area of the cylinder are calculated and printed. (setprecision(4) is used to print two decimal values)
