Write a program that reads in the radius and length of a cylinder and computes the area and volume using the following formulas: area = radius * radius * π volume = area * length

(Compute the volume of a cylinder) Write a program that reads in the radius and length 
of a cylinder and computes the area and volume using the following formulas:
area = radius * radius * π
volume = area * length

#Beginner
In gcc c++ compiler using namespace std;

#include<iostream>
 using namespace std;
 
 int main()
 {
  const double PI = 3.14159;
  double radius , length ;
  cout<<"enter the radius of cylinder :";
  cin>>radius;
  cout<<"enter the length of cylinder :";
  cin>>length;
 
  double area = radius * radius * PI ;
 
  double volume = area * length ;
 
  cout<<" \n area of cylinder is :"<<area<<endl;
  cout<<" \n volume of cylinder is :"<<volume<<endl;
 
 
  return 0;
 }
copy

Output
enter the radius of cylinder :4
enter the length of cylinder :6

 area of cylinder is :50.2654

 volume of cylinder is :301.593

(Population projection) The U.S. Census Bureau projects population based on the  following assumptions: 1.One birth every 7 seconds 2.One death every 13 seconds 3.One new immigrant every 45 seconds  Write a program that displays the population for each of the next five years. Assume  the current population is 312,032,486 and one year has 365 days. Hint: In C++, if two  integers perform division, the result is the quotient. The fractional part is truncated. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { long long int   currentPopulation = 312032486;     int perBirth = 7 ; //second ;     int perDeath = 13 ; //second ;     int perImmigrant = 45 ; //second ;          cout<< "enter year to see population : " ;     int year ; cin>>year; //get year          long long int   yearTosecond = yea...

(Find the number of years) Write a program that prompts the user to enter the min- utes (e.g., 1 billion), and displays the number of years and days for the minutes. For  simplicity, assume a year has 365 days. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { int minutes; cout<< "enter the minutes : " ; cin>>minutes; const int year_per_minutes=365*24*60; const int day_per_minutes=24*60; int year=minutes/year_per_minutes; int day=(minutes%year_per_minutes)/(day_per_minutes); cout<< " " <<minutes<< " minutes is aproximately " <<year<< " years and " <<day<< " days" ; return 0; } copy Output enter the minutes : 1000000000  1000000000 minutes is aproximately 1902 years and 214 days [Program finished] Need of Programmer Need of Programmer ...

(Financial application: calculate tips) Write a program that reads the subtotal and  the gratuity rate, then computes the gratuity and total. For example, if the user enters  10 for subtotal and 15% for gratuity rate, the program displays $1.5 as gratuity and  $11.5 as total. #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { float total , gratuity_rate ; cout<< " enter sub total and gratuity rate :" ; cin>>total>>gratuity_rate; float gratuity = total*gratuity_rate/100; float final_total = gratuity + total; cout<< "gratuity $" <<gratuity<< " final total is $" <<final_total; return 0; } Output enter sub total and gratuity rate :10 15 gratuity $1.5 final total is $11.5 [Program finished]
