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
def sphere_area(radius):
return 4 * math.pi * radius**2
def sphere_volume(radius):
return (4/3) * math.pi * radius**3
radius = float(input("Enter the radius of the sphere: "))
area = sphere_area(radius)
volume = sphere_volume(radius)
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.
