Tracing Code - Trace the code segments showing the variables' values in the columns while circling the final values. 4. # assume the user inputs the values: 9, 8, 2, -1
sum = 0 sum num

print(sum) # the output is:

Pp 4.1 design and implement a class called sphere that contains instance data that represents the sphere’s diameter. define the sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. include methods that calculate and return the volume and surface area of the sphere (see pp 3.5 for the formulas). include a tostring method that returns a one-line description of the sphere. create a driver class called multisphere, whose main method instantiates and updates several sphere objects.

How can you make your column headings stand out?
