#include <cstdlib>
#include <iostream>

using namespace std;
// function main begins program execution
int main(int argc, char *argv[])
{
int pi; //pi to be input by the user
int area; //variable in which area will be stored

printf("Enter the Radius of the Circle\n"); //prompt
printf("Enter the Pi\n"); //prompt

printf("Area of Circle is %d\n", area); //print area

You need to supply more information and understand the problem. Are you looking for a sum of areas of multiple circles, Or a printout of the different circles. Also, are these circles independent or overlapping. You need to understand the problem before you can achieve a solution. How would you do it in real life first?

Here's the question:
modify the above exercise (Exercise 3) to calculate the area of several circles.

THE exercise 3 is the code i pasted above.
any help

Maybe it will be better to declare pi, radius and area as double or float.

If you want to calculate areas of more circles, you can try a loop and then add the areas to the sum.
