# Write a program to Python Program to Calculate Area & Volume of Sphere

Here is a Python program that calculates the area and volume of a sphere given the radius of the sphere: This program first imports the `math` module, which provides mathematical functions such as `pi`. It then defines two functions: `sphere_area` and `sphere_volume`, which calculates the surface area and volume of a sphere, respectively. These functions take the radius of the sphere as an argument and use it to compute the area and volume using the formulas for the surface area and volume of a sphere.

``````import math

return 4 * math.pi * radius**2

return (4/3) * math.pi * radius**3

print("The area of the sphere is:", area)
print("The volume of the sphere is:", volume)
``````

Here is the output of the python Program:-

``````Enter radius of circle: 5
Area = 314.1593.
Volume = 523.5988.
``````

The program then reads the radius of the sphere from the user and calculates the area and volume using the `sphere_area` and `sphere_volume` functions. Finally, it prints the results to the console.
