Description
In this tutorial, we will learn all about the circle ( area, circumference ) with all types of method. Inbuild Methods, function, simple so on. You can write the Program to calculate area of a circle and, also calcuate the operation below...
- Calculate the area of a circle in Python Programming language
- Find the area of a circle using function in Python
- Find the area of a circle using the math module in python
- Python program to calculate the area and circumference of a circle
- Python program to calculate the area and circumference of a circle using an inbuild math module
- Python program to find the area and perimeter of a circle
Calculate the area of a circle in Python Programming language
- Take input from the user using input() function for radius and store in a variable
- Use constant variable to store the value of "PI".
- And, Calculate the area of a circle with the formula area = PI * r *r.
- And, in Last, print the area of circle
r = float(input("Enter the radius of Circle : " ))
PI = 3.14
area = PI * r * r
print("Area : ",area)
'''
#Output:
Enter the radius of Circle : 2
Area : 12.56
'''
Find the area of a circle using function in Python
- defined a function as def area_of_circle().
def area_of_circle(r):
PI = 3.14
return PI * r * r
r = float(input("Enter the radius of Circle : "))
print("Area : %.6f" % area_of_circle(r))
'''
#Output
Enter the radius of Circle : 3
Area : 28.260000
'''
Find the area of a circle using the math module in python
- import math module which is inbuilt module
- take the input radius from the user
- now, calculate the area of using this formula area = math.pi * r * r. The value of "pi" is taken from the "math" module
- And, print the area of circle
import math
r = float(input("Enter the radius of Circle : "))
area = math.pi * r * r
print("Area : ", area)
'''
#Output:
Enter the radius of Circle : 2
Area : 12.566370614359172
'''
Python program to calculate the area and circumference of a circle
- Take input from the user using input() function for radius and store it in a variable.
- use constant to store the value of "PI".
- Now, calculate the area of circle by using formula area = PI * r * r.
- And Caluclating the circumference of a circle, using the formula circumference = 2 * PI * r.
- print the area and circumference of a circle.
PI = 3.14
r = float(input("Enter the radius of Circle : "))
area = PI * r * r
circumference = 2 * PI * r
print("Area of Circle : ", area)
print("Circumference of Circle : ", circumference)
'''
#Output:
Enter the radius of Circle : 5
Area of Circle : 78.5
Circumference of Circle : 31.400000000000002
'''
Python program to calculate the area and circumference of a circle using an inbuild math module
import math
r = float(input("Enter the radius of Circle : "))
area = math.pi * r * r
circumference = 2 * math.pi * r
print("Area of Circle : ",area)
print("Circumference of Circle : ", circumference)
'''
#Output:
Enter the radius of Circle : 5
Area of Circle : 78.53981633974483
Circumference of Circle : 31.41592653589793
'''
Python program to find the area and perimeter of a circle
- Take input from the user using input() function for radius of circle
- use constant to store the value of "PI".
- Calculate the area of circle using the formula area = PI * r * r
- and calculating the perimeter of a circle we will use the formula perimeter = 2 * PI * r
- print the area and perimeter of circle
PI = 3.14
r = float(input("Enter the radius of circle : "))
area = PI * r * r
perimeter = 2 * PI * r
print("Area of Circle : ", area)
print("Perimeter of Area : ", perimeter)
'''
#Output:
Enter the radius of circle : 6
Area of Circle : 113.03999999999999
Perimeter of Area : 37.68
