**Area of circle in python: **In the previous article, we have discussed Python Program to Check if a given Circle lies Completely Inside the Ring formed by Two Concentric Circles

Given the side length of a square, the task is to calculate the area of a circumscribed circle around the given square.

Formula:(pi * s* s)/2

where pi= 3.14159265

s = side length of square.

**Examples:**

**Example1:**

**Input:**

Given side of square = 5

**Output:**

The area of an circumscribed circle is for a given square of side { 5 } = 39.27

**Example2:**

**Input:**

Given side of square = 8

**Output:**

The area of an circumscribed circle is for a given square of side { 8 } = 100.53

## Program for Area of a Circumscribed Circle of a Square in Python

Below are the ways to calculate the area of a circumscribed circle around the given square in python:

### Method #1: Using Mathematical Formula (Static Input)

**Approach:**

- Give the side of a square as static input and store it in a variable.
- Take a variable and initialize it with the pi value of 3.14159265.
- Create a function to say
**Find_areacircumscribdcirle()**which takes the given side length of the square as an argument, and returns the area of a circumscribed circle around the given square. - Inside the function, calculate the area of a circumscribed circle around the given square using the above mathematical formula and store it in a variable.
- Return the above result.
- Pass the given side length of the square as an argument to the
**Find_areacircumscribdcirle()**function and store it in another variable. - Print the above result by rounding off to the 2 places after the decimal point using the round() function.
- The Exit of the Program.

**Below is the implementation:**

# Create a function to say Find_areacircumscribdcirle() which takes the given side # length of the square as an argument, and returns the area of a circumscribed # circle around the given square. def Find_areacircumscribdcirle(sideof_sqre): # Inside the function, calculate the area of a circumscribed circle around the given # square using the above mathematical formula and store it in a variable. circl_area = (sideof_sqre * sideof_sqre * (pi / 2)) # Return the above result. return circl_area # Give the side of a square as static input and store it in a variable. sideof_sqre = 5 # Take a variable and initialize it with the pi value of 3.14159265. pi = 3.14159265 # Pass the given side length of the square as an argument to the # Find_areacircumscribdcirle() function and store it in another variable. fnl_rsltarea = Find_areacircumscribdcirle(sideof_sqre) # Print the above result by rounding off to the 2 places after the decimal point using # the round() function. print("The area of an circumscribed circle is for a given square of side {", sideof_sqre, "} = ", round(fnl_rsltarea, 2))

**Output:**

The area of an circumscribed circle is for a given square of side { 5 } = 39.27

### Method #2: Using Mathematical Formula (User Input)

**Approach:**

- Give the side of a square as user input using the float(input()) function and store it in a variable.
- Take a variable and initialize it with the pi value of 3.14159265.
- Create a function to say
**Find_areacircumscribdcirle()**which takes the given side length of the square as an argument, and returns the area of a circumscribed circle around the given square. - Inside the function, calculate the area of a circumscribed circle around the given square using the above mathematical formula and store it in a variable.
- Return the above result.
- Pass the given side length of the square as an argument to the
**Find_areacircumscribdcirle()**function and store it in another variable. - Print the above result by rounding off to the 2 places after the decimal point using the round() function.
- The Exit of the Program.

**Below is the implementation:**

# Create a function to say Find_areacircumscribdcirle() which takes the given side # length of the square as an argument, and returns the area of a circumscribed # circle around the given square. def Find_areacircumscribdcirle(sideof_sqre): # Inside the function, calculate the area of a circumscribed circle around the given # square using the above mathematical formula and store it in a variable. circl_area = (sideof_sqre * sideof_sqre * (pi / 2)) # Return the above result. return circl_area # Give the side of a square as user input using the float(input()) function and # store it in a variable. sideof_sqre = float(input("Enter some random number = ")) # Take a variable and initialize it with the pi value of 3.14159265. pi = 3.14159265 # Pass the given side length of the square as an argument to the # Find_areacircumscribdcirle() function and store it in another variable. fnl_rsltarea = Find_areacircumscribdcirle(sideof_sqre) # Print the above result by rounding off to the 2 places after the decimal point using # the round() function. print("The area of an circumscribed circle is for a given square of side {", sideof_sqre, "} = ", round(fnl_rsltarea, 2))

**Output:**

Enter some random number = 8 The area of an circumscribed circle is for a given square of side { 8.0 } = 100.53
