1R

(6.37 × 106 m)(10−3 km m) = 6.37 × 103 km,

A = 2π R = 2xπ 6.37 x 106km = 40023

B= 4π R2 = 4π 6.37 x 103 km 2 = 509.90

C = 44π/3*r3= 4π/3 6.37 ×103 km 3 = 1.082

3 R

a 1km x 103 m = (103 m)(106 μ m /m) = 100000000 μm

b γd/1μ = 9.144μm

4R

A = 0.80 x1p/2.54x6paica/1p =1.889picas

B = 0,80x1/2.54 x 6/1 x12/1=22.677

5R

10 furlong; 201.168m;

(201.168m).1vara/5.0292m = 40 varas

1.0 furlong 201,168m =

(201.168m)x1/20.117m = 10 cadeias

4.0 furblongs

(4.0) 40/1varas = 160 varas

4.0 flurlong

(4.0) 10/1 =40 cadeias
