### Understanding the Concept of Sphere:

A sphere is a perfectly symmetrical geometrical object that is defined as a set of points that are equidistant from a single point called the center. The surface of a sphere is curved, and it has no edges or corners. The sphere is an essential mathematical concept used in various fields such as science, engineering, and architecture.

### Formulas for Area and Volume of Sphere:

- To calculate the area and volume of a sphere, we use the following formulas:

- Area of Sphere = 4πr²

- Volume of Sphere = (4/3)πr³

where π (pi) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter, and r is the radius of the sphere.

### Python Program to Calculate the Area and Volume of Sphere:

Now, let's write a Python program to calculate the area and volume of a sphere. Follow the below steps to create the program:

Step 1:

Take the radius of the sphere as input from the user using the input() function and store it in a variable r.

Step 2:

Calculate the area of the sphere using the formula Area = 4πr² and store it in a variable called an area.

Step 3:

Calculate the volume of the sphere using the formula Volume = (4/3)πr³ and store it in a variable called volume.

Step 4:

Print the calculated area and volume of the sphere using the print() function.

#### The Python code for the above steps is as follows:

pi = 3.14159

r = float(input("Enter the radius of the sphere: "))

area = 4 * pi * r ** 2

volume = (4 / 3) * pi * r ** 3

print("The area of the sphere is: ", round(area, 2))

print("The volume of the sphere is: ", round(volume, 2))

In the above code, we have used the float() function to convert the user input from string to float data type because the radius of the sphere can be a decimal value.

### Conclusion:

In this post, we have learned how to write a Python program to calculate the area and volume of a sphere using the formulas. We have also discussed the concept of the sphere and the significance of Python in scientific computing. Writing programs in Python is a fun and exciting task that can enhance your analytical and logical thinking abilities. By following the above steps, you can easily calculate the area and volume of a sphere in Python. Happy learning!
