Program to find area and circumference of circle using radius in python; Through this tutorial, i am going to show you how to find area and circumference of circle using radius in python.
There mathematical formula to find or calculate area and circumference of circle using radius:
- Diameter of a Circle = 2r = 2 * radius
- Area of a circle is: A = πr² = π * radius * radius
- Circumference of a Circle = 2πr = 2 * π * radius
Python Program to Find Area and Circumference of Circle
See the following python programs to find or calculate the area and circumference of circle; as shown below:
- Python Program to find Diameter Circumference and Area Of a Circle
- Python Program to Calculate Diameter Circumference and Area Of a Circle using Function
Python Program to find Diameter Circumference and Area Of a Circle
- Get input the radius of a circle from user in program.
- Using the radius value and formula to calculate the Circumference, Diameter, and Area Of a Circle,
- Diameter of a Circle = 2r = 2 * radius,
- Area of a circle are: A = πr² = π * radius * radius
- Circumference of a Circle = 2πr = 2 * π * radius.
- Print Area and Circumference of Circle.
# Python Program to find Diameter, Circumference, and Area Of a Circle PI = 3.14 radius = float(input(' Please Enter the radius of a circle: ')) diameter = 2 * radius circumference = 2 * PI * radius area = PI * radius * radius print(" \nDiameter Of a Circle = %.2f" %diameter) print(" Circumference Of a Circle = %.2f" %circumference) print(" Area Of a Circle = %.2f" %area)
After executing the python program, the output will be:
Please Enter the radius of a circle: 5 Diameter Of a Circle = 10.00 Circumference Of a Circle = 31.40 Area Of a Circle = 78.50
Python Program to Calculate Diameter Circumference and Area Of a Circle using Function
- Create functions to calculate the Circumference, Diameter, and Area Of a Circle in program.
- Get input the radius of a circle from user in program.
- Print Area and Circumference of Circle.
# Python Program to find Diameter, Circumference, and Area Of a Circle import math def find_Diameter(radius): return 2 * radius def find_Circumference(radius): return 2 * math.pi * radius def find_Area(radius): return math.pi * radius * radius r = float(input(' Please Enter the radius of a circle: ')) diameter = find_Diameter(r) circumference = find_Circumference(r) area = find_Area(r) print("\n Diameter Of a Circle = %.2f" %diameter) print(" Circumference Of a Circle = %.2f" %circumference) print(" Area Of a Circle = %.2f" %area)
After executing the python program, the output will be:
Please Enter the radius of a circle: 56 Diameter Of a Circle = 112.00 Circumference Of a Circle = 351.86 Area Of a Circle = 9852.03
