In this program, with the help of python, we are calculating the area of the circle.

Area of the circle is equal to the **3.14 * r * r**, where r is the radius of the circle.

Area of the circle is the number of square units inside the circle.

**For example:**

Input: r = 5

**Output:** 3.14 * 5 * 5 = 78.5

- Input the radius from the user.
- Calculate the area of the circle using 3.14 * r * r.
- Print the area.
- Exit

**Algorithm:**

**Code:**

```
r = int(input("Enter the radius:"))
area = 3.14*r*r
print("The area is:", area)
```

**Output****:**

```
Enter the radius : 2
The area is : 12.56
```
