You lay down the paper clip on a sheet of paper and use one of the pencils to hold the clip in place pointed side down. Next you take the other pencil and start drawing the circle. You can find a video on youtube that illustrates it. My son had this as a homework assignment, I found it very useful.

A standard A4 sheet of paper is 21.0 x 29.7 cm, for a total area of 623.7 sq cm. A US standard A-size sheet of paper is 8.5 x 11 inches, which is 21.59 x 27.94 cm, for a total area of 603.2246 sq cm.
There are no angles: the only intersections are of curves.

Depends on the size of the paper clip. Paper clips come in a range of sizes. Agreed. Also: The weight of one standard paper clip = 0.00043kg x 9.8m/s2 = 0.004214 N, or 0.000947345 lbf. So if you divide 1 lbf by the weight of a standard paper clip given then with that size of paper clip it would take about 1,056 to make a pound.
