Python Program to find area of a circle

  

                        Area of a circle = πr2  

                                  r = radius of a circle
 To find area of a circle we need to follow the formula. Area of a circle is πr2 . r is the radius of a circle.  

      Input:

        5
   Output: 

        area of a circle is 78.5

    Explanation:

        r = 5, π = 3.14
    area of a circle= 3.14*(r*r) = 3.14*5*5 = 78.5 

      Code:

        r=input()
        print("area of a circle is ",3.14*(r*r) )
