Organelles

You receive the radius of a typical human skin cell, as well as two 
dictionaries, one with the radii of various organelles and one with the 
number of these organelles typically found in a skin cell. Write a piece of 
code that calculates the volume percentage each of these organelles takes up 
in the cell. You may assume that the organelles are spherical.

Store the volume percentages in a dictionary named `volume_percentages` with 
the same keys as the original two dictionaries. Do not round the percentages.

pi = 3.1415

cell_radius = 40    # micrometers

organelle_radius = {"nucleus" : 15,
                "mitochondrion" : 3,
                "golgi" : 5e-1,
                "ribosome" : 1e-3}  # all in micrometers

organelle_number = {"nucleus" : 1,
                "mitochondrion" : 200,
                "golgi" : 1,
                "ribosome" : 10e7}
