Express the weight of the main axle of the 1893 Ferris wheel in kilograms.

WITCHER [35]

Answer:

40514.837 kg

Step-by-step explanation:

The weight of the main axle of the 1893 ferris wheel built by George Washington Gale Ferris Jr. in Chicago, USA was 89,320 pounds (lb).

1 kg=2.20462 pounds (lb)

$\Rightarrow 1 lb=\frac{1}{2.20426}$

$\Rightarrow 1 lb=0.453592 kg$

$\Rightarrow 89320 lb=89320\times 0.453592$

$\therefore 89320 lb=40514.837 kg$
