Question

Write and test a program that computes the area of a circle. Request a number representing a radius as input from the user. Use the formula 3.14 × radius2 to compute the area. Output this result with a suitable label.

Answer 1

Since you have not mentioned the language of your preference, I am providing the code in C++.

CODE

#include <iostream>

using namespace std;

int main() {

double radius;

cout << "Enter the radius of the circle: ";

cin >> radius;

cout << "The area of the circle is: " << 3.14 * radius * radius;

}
