Answer:
The angle the minute hand travels in 4 full rotations is [tex]8\ pi\ radians[/tex]
Step-by-step explanation:
We know that one complete rotation is given by :
[tex]1\ rotation=1\ hour[/tex]
and [tex]1\ hour=60\ minutes=2\ \pi[/tex]
So, [tex]1\ rotation=2\ \pi[/tex]
Using unitary method we can find the minute hand travel in 4 rotations.
[tex]\because 1\ rotation=2\ \pi\ radians[/tex]
So, [tex]4\ rotation=8\ \pi\ radians[/tex]
Hence, this is the required solution.
