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
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;
}
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
