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

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.

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
