43)write a program to evaluate and display the volume of a cyclinder given its area and height.

#include<iostream>
using namespace std;
#define PI 3.14
int main()
{ float radius,height,volume;
  cout<<"enter radius of cylinder  "<<endl;
  cin>>radius;
  cout<<"enter height of cylinder  "<<endl;
  cin>>height;
  volume=PI*radius*radius*height;
 cout<<"the volume of cylinder is "<<volume;
}
