Calculate the Area And Circumference of a Circle Based on its Radius

 Calculate the Area and Circumference of a circle based on its radius

{Formula :- Area of Circle = (3.14*radius^2) (Assuming as pi = 22/7 ~= 3.14)

                 Circumference of Circle = (2*3.14*radius)}

Input is Shown Below :

Code :

            # Lets Find the Area & Circumference of a Circle

#Code by IAH (Infinity Aggarwal Harshul)

#Area of Circle Formula is (3.14*r*r) = (pi*radius of circle)

#Circumference of Circle Formula is (2*3.14*r) = (2*pi*radius of circle)

a = int(input("Enter Radius : "))     #here we are taking user input value

b  = int(input("Enter Length : "))

print ("Area :",(3.14*a*a)) #here print function will give output according to assigned opertors

print ("Circumference :",(2*3.14*a))

#Now the final output will according the formula mentioned below

Output is Shown Below :     

Explanation:

1. A variable a is taken for user input value
2. And we simply print the area of circle using direct formula inside it
3. And we simply print the circumference of circle using direct formula inside it
4. At last, we can see the results showing the calculated answer according to the formula typed inside them
