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

(Geometry: distance of two points) Write a program that prompts the user to enter  two points (x1, y1) and (x2, y2) and displays their distance between them.The formula for computing the distance is  √ (x2 - x1)²+ (y2 - y1)² . Note that you  can use pow(a, 0.5) to compute √a.  #Beginner In gcc c++ compiler using namespace std; #include<iostream> #include<cmath> using namespace std; int main() { float x1,y1,x2,y2; cout<< "Enter x1 and y1 :" ; cin>>x1>>y1; cout<< "Enter x2 and y2 :" ; cin>>x2>>y2; float distance=pow((pow(x2-x1,2))+pow(y2-y1,2),0.5); cout<< "The distance between the two points is :" <<distance; return 0; } copy Output Enter x1 and y1 :1 9 Enter x2 and y2 :3 -5 The distance between the two points is :14.1421 [Program finished] Need of Programmer Need of Programmer

(Science:calculating energy ) Write a program that calculates the energy needed to  heat water from an initial temperature to a final temperature. Your program should  prompt the user to enter the amount of water in kilograms and the initial and final  temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184  where M is the weight of water in kilograms, temperatures are in degrees Celsius, and  energy Q is measured in joules.  #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { float M,finalTemperature,initialTemperature; cout<< "Enter te amount of water in kilograms :" ; cin>>M; cout<< "Enter the initial temperature :" ; cin>>initialTemperature; cout<< "Enter te finalTemperature :" ; cin>>finalTemperature; float Q=M*(finalTemperature-initialTemperature)*4184; cout<< "Th...
