Spherevolume = (4.0 / 3.0) * pival * sphereradius * sphereradius * sphereradius ;

The program in Python is as follows:

pival = 3.142

sphereradius = float(input("Radius: "))

spherevolume = * * sphereradius * * sphereradius

print(spherevolume)

Explanation:

The missing part of the program is to calculate the volume of a sphere.

The program in Python (in the answer section) is implemented using the already used variables.

Initialize pi

pival = 3.142

Get input for radius

sphereradius = float(input("Radius: "))

Calculate the volume

spherevolume = * * sphereradius * * sphereradius

Print the calculated volume

print(spherevolume)
