Python program to find area of circle

sure! here is a tutorial on how to write a python program to find the area of a circle.

1. first, you need to know the formula to calculate the area of a circle. the formula is: area = π * r^2, where r is the radius of the circle and π (pi) is a mathematical constant approximately equal to 3.14159.

2. in python, you can use the math module to access the value of pi and perform mathematical operations. so, you need to import the math module at the beginning of your program.

3. next, you can define a function that takes the radius of the circle as an input parameter and calculates the area using the formula mentioned above.

4. here is a sample python program to find the area of a circle:

in this program:
- we import the math module to access the value of pi.
- we define a function `calculate_circle_area` that takes the radius as input, calculates the area using the formula, and returns the result.
- we prompt the user to enter the radius of the circle.
- we call the `calculate_circle_area` function with the user-provided radius and store the result in the `area` variable.
- finally, we print the calculated area with two decimal places.

you can run this program in a python interpreter or a code editor to find the area of a circle for a given radius.
