Textbook Question
Chapter 7, Problem 7.16CP
For the following computer problems, any appropriate software may be used. Input prompts should fully explain what is required of the user (the program should be user-friendly). The resulting output should be well labeled and self-explanatory. For spreadsheet problems, any appropriate software may be used.
7.16 Write a program that will calculate the location of the centroid of a semicircle (measured from the daimeter line). This may be accomplished by dividing the area into slices of uniform width, either parallel or perpendicular to the diameter, and applying Equation (7.4). 
User input is to be the radius and width of the slice. Check the result with that obtained from Table 2. 
Note how the accuracy varies with the choice of the slice width.
