Menghitung luas lingkaran dan menentukan besar, sedang, kecil.

#include <iostream>

using namespace std;

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char** argv) {

int n, p, phi;

phi=22/7;

cout<<"masukkan jari jari : ";

cin>>n;

p=4/3*phi*n*n*n;

if(p<100){

cout<<p<<" : angka kecil"<<endl;

}

else if(p<499){

cout<<p<<" : angka sedang"<<endl;

}

else if(p>500){

cout<<p<<" : angka besar"<<endl;

}

return 0;
