1. Various geometric formulas are given in Appendix E. (a) Expressing the radius of the Earth as R = (6.37 × 106 m)(10−3 km m) = 6.37 × 103 km, its circumference is s = 2π R = 2π (6.37 × 103 km) = 4.00×104 km. (b) The surface area of Earth is ( )A = 4π R2 = 4π 6.37 × 103 km 2 = 5.10 × 108 km2. (c) The volume of Earth is ( )4 3 4 6.37 103 km 3 1.08 1012 km3. 3 3 V R π π = = × = × 2. The conversion factors are: 1 gry =1/10 line , 1 line =1/12 inch and 1 point = 1/72 inch....
