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

Result

l =  171 m

#### Solution:

$D = 1.7 \ m \ \\ o = \pi \cdot \ D = 3.1416 \cdot \ 1.7 \doteq 5.3407 \ m \ \\ n = 32 \ \\ \ \\ l = n \cdot \ o = 32 \cdot \ 5.3407 \doteq 170.9026 = 171 \ \text { m }$
