I know these questions are simple, but for some reason I can not seem to find the right answers.(adsbygoogle = window.adsbygoogle || []).push({});

1. [HRW7 1.P.002.] A "gry" is an old English measure for length, defined as 1/10 of a line, where "line" is another old English measure for length, defined as 1/12 inch. A common measure for length in the publishing business is a "point", defined as 1/72 inch. What is an area of 0.75 gry^2 in terms of points squared (points^2)?

6. [HRW7 1.P.020.] Gold, which has a mass of 19.32 g for each cubic centimeter of volume, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber.

(a) If a sample of gold, with a mass of 66.31 g, is pressed into a leaf of 4.800 µm thickness, what is the area of the leaf?

(b) If, instead, the gold is drawn out into a cylindrical fiber of radius 1.000 µm, what is the length of the fiber?

For the first one I find a gry to be 1/120 inch. To convert I do .75 gry^2 * (0.6 points^2/1 gry^2) = .45 points^2

Apparently this is wrong.

For the second one I get 7.15 m for (a).
