Python program to calculate surface area of a circle
Allow run into python programme to calculate the surface area of a circle.
- Firstly, we will take input from the user using the input() part for radius and store information technology in a variable.
- We tin use constant to shop the value of 'pi'.
- At present, nosotros will calculate the surface area of a circle past using the formula area = PI * r * r.
- And at terminal, impress the area of a circle to get the output.
Case:
PI = 3.fourteen r = float(input("Enter the radius of a circle:")) area = PI * r * r impress("Area of a circle = %.2f" %area) You lot can refer to the below screenshot to see the output for python programme to summate the area of a circle
The above code, we can use to calculate area of a circle in Python.

Python program to observe area of a circle using function
Hither, we will meet python program to observe the expanse of a circumvolve using function.
- In this case, I take divers a function as def findArea(r).
- We can store the value PI = iii.14 which is fixed.
- The function is returned every bit render PI * (r * r)
- The function findArea(half dozen) is called and it will print the output.
Example:
def findArea(r): PI = three.14 return PI * (r*r); print("Area of circle = %.6f" % findArea(6)); You can refer to the below screenshot to see the output for the python programme to discover the area of a circle using the function.

Observe area of a circle using Python math module
Now, we volition run into python program to discover area of a circle using the math module.
- In this case, we will import math module which is an inbuilt module.
- Nosotros will take the radius as an input from the user.
- Now, we will summate the area of a circle by using the formula area = math.pi * r * r. The value of "pi" is taken from the "math" module.
- And at last, print the area of a circle to get the output.
Instance:
import math r = bladder(input("Enter the radius of a circle:")) area = math.pi * r * r print("Surface area of a circumvolve = %.2f" %area) You lot can refer to the beneath screenshot to see the output for the python program to detect the area of a circle using the math module.
The to a higher place lawmaking, we can use to find area of a circumvolve using Python math module.

Python program to summate surface area and circumference of a circumvolve
Let's see python programme to calculate the expanse and circumference of a circle.
- Firstly, we volition take input from the user using the input() function for radius and store it in a variable.
- We can use constant to store the value of 'pi'.
- Now, nosotros will calculate the area of a circumvolve by using the formula area = PI * r * r.
- And for calculating the circumference of a circle nosotros will apply the formula circumference = 2 * PI * r.
- And at final, print the area and circumference of a circle to get the output. The value is formatted up to two decimal places using %.2f.
Example:
PI = 3.14 r = float(input(' Please Enter the radius of a circle: ')) surface area = PI * r * r circumference = 2 * PI * r print(" Expanse Of a Circumvolve = %.2f" %surface area) impress(" Circumference Of a Circle = %.2f" %circumference) You can refer to the beneath screenshot to encounter the output for the python plan to calculate the area and circumference of a circle.
This is the Python program to calculate area and circumference of a circle.

Python program to calculate the area and circumference of a circle using an inbuilt math module
Here, we will encounter python program to summate the expanse and circumference of a circumvolve using an inbuilt math module.
- Firstly, nosotros volition import math module which is an inbuilt module.
- We volition accept input from the user using the input() function for radius and store information technology in a variable.
- Now, we will summate the area of a circumvolve past using the formula area = math.pi * r * r.
- And for calculating the circumference of a circle we will use the formula circumference = ii * math.pi * r.
- And at last, impress the area and circumference of a circle to get the output. The value is formatted up to 2 decimal places using %.2f.
Example:
import math r = float(input(' Please Enter the radius of a circumvolve: ')) expanse = math.pi * r * r circumference = 2 * math.pi * r print(" Expanse Of a Circle = %.2f" %expanse) print(" Circumference Of a Circumvolve = %.2f" %circumference) You lot tin refer to the below screenshot to see the output for the python program to calculate the area and circumference of a circle using an inbuilt math module.
Python programme to observe surface area and perimeter of a circle
At present, we will see python programme to find the area and perimeter of a circle
- Firstly, we volition take input from the user using the input() part for radius and store it in a variable.
- We have used 3.14 the value of pi in the formula.
- Now, we will summate the area of a circle by using the formula area = 3.xiv* r * r.
- And for calculating the perimeter of a circumvolve we will utilize the formula perimeter = 2*three.xiv*r
- And at terminal, print the area and perimeter of a circle to get the output.
Example:
r=float(input("Enter the Radius of circle: ")) expanse = 3.fourteen*r*r perimeter = 2*three.xiv*r print("Surface area of Circle: ",surface area) print("Perimeter of Circumvolve: ",perimeter) You lot can refer to the below screenshot to see the output for the python program to find the area and perimeter of a circle.
The to a higher place code, nosotros can use to find area and perimeter of a circle in Python.
Python plan to calculate area of a circle using class
Permit see python program to calculate the area of a circle using class.
- In this example, we have created a form named "Circle" and it has an attribute radius as r.
- The constructor of the form initiates the attribute using the __init__function.
- We have used 3.14 the value of pi in the formula.
- The method "area" is created to calculate the area of a given circle.
- An instance of the class "Circle" is created equally "obj" and the method is invoked to brandish the output.
Example:
course Circumvolve: def __init__(cocky, r): cocky.radius = r def area(cocky): return 3.14 * (self.radius ** 2) obj = Circle(8) print("Surface area of circle:",obj.area()) You can refer to the below screenshot to run across the output for the python programme to calculate the area of a circle using course.
The above Python code is to summate expanse of a circle using class.
Python program to calculate surface area and perimeter of a circle using class
Hither, we will come across python program to summate the area and perimeter of a circle using course
- In this example, we have created a course named "Circumvolve" and it has an attribute radius equally r.
- The constructor of the class initiates the attribute using the __init__function.
- We have used iii.fourteen the value of pi in the formula.
- The two methods "area" and "perimeter" are created to calculate the area of a given circumvolve.
- An instance of the class "Circle" is created every bit "obj" and the method is invoked to display the output.
Instance:
class Circle: def __init__(self, r): self.radius = r def area(cocky): return 3.14 * (cocky.radius ** 2) def perimeter(cocky): return 2*3.14*cocky.radius obj = Circle(3) impress("Area of circle:",obj.area()) print("Perimeter of circle:",obj.perimeter()) You can refer to the below screenshot to meet the output for the python plan to summate the area and perimeter of a circle using class.
