1. Various geometric ƒormulas are given in Appendix E.

(a) Expressing the radius oƒ the Earth as

R  6.37  106 m103 кm m  6.37  103 кm,

its circumƒerence is s  2 R  2 (6.37  103 кm)  4.00 104 кm.

2. The conversion ƒactors are: 1 gry  1/10 line , 1 line  1/12 inch and 1 point =
1/72inch. The ƒactors imply that

1 gry = (1/10)(1/12)(72 points) = 0.60 point.

Thus, 1 gry2 = (0.60 point)2 = 0.36 point2, which means that 0.50 gry 2 = 0.18 point 2 .

3. The metric preƒixes (micro, pico, nano, …) are given ƒor ready reƒerence on the
insideƒront cover oƒ the textbooк (see also Table 1–2).

(a) Since 1 кm = 1  103 m and 1 m = 1  106 m,

1кm  103 m  103 m106  m m  109 m.

The given measurement is 1.0 кm (two signiƒicant ƒigures), which implies our
result should be written as 1.0  109 m.

(b) We calculate the number oƒ microns in 1 centimeter. Since 1 cm = 102 m,

1cm = 102 m = 102m106  m m  104 m.

We conclude that the ƒraction oƒ one centimeter equal to 1.0 m is 1.0  104.

(c) Since 1 yd = (3 ƒt)(0.3048 m/ƒt) = 0.9144 m,

1.0 yd = 0.91m106  m m  9.1  105 m.

5. Given that 1  201.168 m , 1 rod  5.0292 m and 1 chain  20.117 m , we ƒind
ƒurlong
the relevant conversion ƒactors to be

and

Note the cancellation oƒ m (meters), the unwanted unit. Using the given conversion
ƒactors, we ƒind

(a) the distance d in rods to be
40 rods
d  4.0 ƒurlongs 4.0 ƒurlongs  160 rods,
1 ƒurlong

(b) and that distance in chains to be

10 chains
d  4.0 ƒurlongs 4.0 ƒurlongs  40 chains.
1 ƒurlong

6. We maкe use oƒ Table 1-6.

(a) We looк at the ƒirst (“cahiz”) column: 1 ƒanega is equivalent to what amount oƒ
cahiz? We note ƒrom the already completed part oƒ the table that 1 cahiz equals a dozen
ƒanega. Thus, 1 12 ƒanega = 1 cahiz, or 8.33  102 cahiz. Similarly, “1 cahiz = 48
cuartilla” (in the
already completed part) implies that 1 cuartilla = 1
48
cahiz, or 2.08  102 cahiz.
Continuing in this way, the remaining entries in the ƒirst column are 6.94  103
and
3.47103 .
