Answer 2

#include<iostream>

using namespace std;

int main()

{

float rad, area;

float circum;

cout<<"Enter the Radius of Circle: ";

cin>>rad;

area = 3.14*rad*rad;

cout<<"\nArea of Circle = "<<area;

circum=2.0*3.14*rad;

cout<<"\nCircumference of Circle = "<<circum;

cout<<endl;

return 0;
