I have no idea how to start, please help me..

Objective - To exercise some of the Python's interactive I/O formatting options to compose, manipulate and format computed values of a user-defined (a.ka, "custom) class that models a Sphere. Specifications - Define some global functions that will take a number and output it to the screen using decimal, hexadecimal, scientific, or binary notation depending on the characteristic being output (see sample output below). The values passed to these global functions will be values returned methods from of a user-defined Sphere class. Given an object of a Sphere class with a single instance variable, Radius, define methods in the class that compute and return values for the Circumference and volume of the object. Using this class and the global functions, print out the data in columns for spheres that have radii of (as a minimum) 20 to 30 in increments of 1 unit. The output should look something like the following (NOTE the centering between the margins required for the first three lines of output; RADIUS+++++++++++++++++++++VOLUME+ ++ ++++++RADIUS -CIRCUMFERENCE HEXIDECIMAL SCIENTIFIC DECIMAL BINARY 3.35e+04 20. 21 Ob00010100.

The Sphere class encapsulates the necessary data item and methods to manage this data item and accomplish the calculations for a Sphere object. The global formatting functions receive a decimal number parameter and cause it to be formatted in the appropriate form and the formatted form then returned.
