Answer 1

SOLUTION TO THE ABOVE QUESTION

SOLUTION CODE

#include<iostream>
using namespace std;

int main()
{


	//propmt the user to enter the radius of the circle
	cout<<"\nEnter the radius of the circle: ";
	double radius;
	cin>>radius;
	double PI = 3.1415;
	double area_of_the_circle = PI*radius*radius;
	cout<<"\nThe radius of the circle = "<<radius<<endl;
	cout<<"The area of the circle = "<<area_of_the_circle<<endl;


}
