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)
[tex]\Rightarrow 1 lb=\frac{1}{2.20426}[/tex]
[tex]\Rightarrow 1 lb=0.453592 kg[/tex]
[tex]\Rightarrow 89320 lb=89320\times 0.453592[/tex]
[tex]\therefore 89320 lb=40514.837 kg[/tex]
