Question

1. Write a program that reads in the radius and length of a cylinder and computes volume using the following formulas:

area = radius * radius * PI

volume = area * length

Answer 1

//Program:

#include<iostream>
using namespace std;
int main()
{
   int radius, length;
   float area, volume;
   cout<<"Enter the radius:";
   cin>>radius;                 //reading the radius
   cout<<"Enter the length:";
   cin>>length;                 //reading the length
   area=radius*radius*3.14;     //calculating the area
   volume=area*length;          //calculating the volume
   cout<<"Area:"<<area<<endl;    //printing the area
   cout<<"Volume:"<<volume;      //printing the volume
   return 0;
}

//Output:
