How to use the "Input" command-- specific problem help

I don't understand how to do the input command.. can someone help me?

The figure attached shows a cylindrical tank of height H and radius r, with a spherical cap on each end (also of radius r). The height of the liquid in the tank is h. Use the input command to obtain values for H, r & h and compute the volume of liquid in the tank.

The calculation of the volume of liquid in the tank depends upon the relationship between h, H and r:

• If h is less than r, we need the volume of a partially-filled sphere

• If h is greater than r but less than H-r, we need the volume of a fully- filed hemisphere plus the volume of a cylinder of height h-r

• If h is greater than H-r, we need the volume of a fully-filled sphere, plus the volume of a cylinder of height H-2r, minus the partially empty upper hemisphere of height H-h

• If h is greater than H, the function should generate an error message (using error)

The input command ask for a value from the user, for example

A = input('Enter value for h: ')

will show on command prompt:

Enter value for h:

Where the user will provide the value and that value will be store in the variable, here A.
