Write two functions var_input() and volume(), where var_input() accepts the input of the radius of a sphere and volume() returns the volume of the sphere up to 4 decimal points.

Program :

def var_input(): #input function which takes the radius as input.

 radius= float(input("Enter the radius of the sphere")) #statemet to take the inputs.

 volume(radius)  /#call the volume function.

def volume(radius):  #definition of volume function.

   print("The volume of the sphere is :"+"{:.2f}".format((4/3)*(22/7)*radius*radius*radius)) # print the volume of the sphere.

var_input() # calling the input function.

Output:
