Homework Answers

The number of lines that can be printed on a paper depends on the paper size, the point size of each character in a line, whether lines are double-spaced or single-spaced, the top and bottom margin, and the left and right margins of the paper. Assume that all characters are of the same point size and all lines are either single-spaced or double spaced. Note that 1 inch = 72 points. Moreover, assume that the lines are printed along with the width of the paper. For example, if the length of the paper is 11 inches and width is 8.5 inches, then the maximum length of a line is 8.5 inches. Write a c# .net program that calculates the number of characters in a line and the number of lines that can be printed on a paper based on the following input from the user:

a. The length and width, in inches of the paper

b. The top, bottom, left, and right margins

c. The point size of a line

d. If the lines are double-spaced, then double the point size of each character

Provide a proper GUI for the user.

The volume of a sphere is 4/3πr³, where π has the value of "pi" given in Section 2.1 of your textbook. Write a function called print_volume (r) that takes an argument for the radius of the sphere, and prints the volume of the sphere.

Call your print_volume function three times with different values for radius.

Include all of the following in your Learning Journal:

• The code for your print_volume function.

The inputs and outputs to three calls of your print_volume.
