The towing wheel has a diameter of 1.7 meters. How many meters does the elevator cage lower when the wheel turns 32 times?

Correct result:

l =  171 m

Solution:

D=1.7 m o=π D=3.1416 1.75.3407 m n=32  l=n o=32 5.3407=171 mD=1.7 \ \text{m} \ \\ o=\pi \cdot \ D=3.1416 \cdot \ 1.7 \doteq 5.3407 \ \text{m} \ \\ n=32 \ \\ \ \\ l=n \cdot \ o=32 \cdot \ 5.3407=171 \ \text{m}
