Mr. David decided to try a new method to help his students visualize three-dimensional figures in class. First, he cut a rectangle out of heavy paper and taped it to the edge of an unsharpened pencil. He then locked the pencil into a drill and turned the drill on. As the drill rotated, the pencil turned and so did the rectangle, producing an image of a cylinder. Which three-dimensional figure would Mr. David be able to illustrate if he taped a right triangle to the pencil?

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
