# WAP in C++ to Find the Area and Circumference of a circle

The Program in C++ to Find the Area and Circumference of a circle is given below:

``````#include <iostream>
#include <cmath>
using namespace std;

int main() {

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

area = M_PI * pow(radius, 2);
circumference = 2 * M_PI * radius;

cout << "Area of the circle: " << area << endl;
cout << "Circumference of the circle: " << circumference << endl;

return 0;
}
``````

## Output:

Enter the radius of the circle: 56
Area of the circle: 9852.03
Circumference of the circle: 351.858

## Pro-Tips💡

In this program, the user is prompted to enter the radius of the circle.

This value is then stored in the variable ‘`radius'`.

The area of the circle is calculated using the formula ‘`area = M_PI * pow(radius, 2)`‘, and the circumference is calculated using the formula ‘`circumference = 2 * M_PI * radius`‘.

The resulting area and circumference are then displayed on the screen.

Note: M_PI is a predefined constant in C++ for pi (3.14159265358979323846)

Also, ‘`pow(x, y)`‘ is a library function in C++ that returns the value of x raised to the power of y.
