Answer:
The correct program to this question can be given as:
Program:
//header file
#include<iostream> //include header file
using namespace std;
//main
int main() //defining method main
{
double radius,area=0; //defining variables
double PI=3.14; //defining variable PI and assign value
cout <<"Enter the radius: "; //message
cin >> radius; //input value by user
area = PI * radius * radius; //formula to calculate area
cout << "Area: "<< area << endl; //print area
return 0;
}
Output:
Enter the radius: 3.0
Area: 28.26
Explanation:
In the above program code, a header file is included. In the next line, the main method is defined, which contain three double type variable that is "radius, area, and PI".
- The radius variable is used to take input by the user, and the area variable is to calculate the area of the circle, and the PI is used to hold a constant value, which is "3.14".
- After taking user input in radius variable the area variable has used the formula of the circle, which calculates a value and in the last print, the function uses "cout", that prints area variable value.
yes, probably not, if you dont know anyone who can do it cheap or has the materials
