Volume of Cone using C++ Programming Language

Volume of Cone :

V =  3.14 * r * r * h  /  3

where

r ==> radius

h==> height

Algorithm:

Two input values , radius and height , which are floating point numbers so type should be double.

Program code:

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

double rad , height , volume ;

char redo;

cout<<endl;

cout<<"*********************************"<<endl;

cout<<"         Volume of Cone          "<<endl;

cout<<"*********************************"<<endl<<endl;

do

{

  cout<<"  Enter radius  =  " ;

  cin>> rad;

  cout<<endl<<endl;

  cout<<"  Enter Height  =  ";

  cin>> height;

  cout<<endl<<endl;

  volume = ( 3.14 * rad * rad * height ) / 3 ;

  cout<<"  Volume of cone is  =  " << volume;

  cout<<endl<<endl;

  

  cout<<"*********************************"<<endl<<endl;

  cout<<"Enter y or Y to for another calculation  =  ";

  cin>>redo;

  cout<<endl<<endl;

    } while(redo == 'y' || redo == 'Y');

   

   getch();

}

Output: After compile and run , the output of above program code is like this
