Given:
The tower at Philadelphia City Hall contains four clocks that have a radius of about 3.96 meters
Question asked:
Find how far the minute hand travels after each number of rotations around the clock face.
Solution:
Radius, r = 3.96 meters
As we have to find distance traveled by minute hand, we will find circumference of circular clock:-
Hence, we found that at one rotation (distance traveled) of minute hand of each clock is 24.89 meters.
Now, we will find distance traveled by 4 minute hand of 4 clocks =![24.8914\times4=99.5656\ meters](/tpl/images/0563/5292/f4ebc.png)
Therefore, minute hand travels 99.57 meters distance after each number of rotations around the clock face.
