Consider the following C+ + program in which the statements are in the incorrect order. Rearrange the statements so that itprompts the user to input the radius of a circle and outputs the area and circumference of the circle-#include {int. main () cout <> radius; cout << endl; double radius; double area; using namespace std; return 0; cout << "Area = ' << area << endl; area - PI * radius * radius;

The correct program to this question can be given as:

Program:

//header file

#include / /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.
