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.
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.
r = int(input("Enter the radius:")) area = 3.14*r*r print("The area is:", area)
Enter the radius : 2 The area is : 12.56
