Question

What is the total radian measure of the angle the minute hand travels in 4 full rotations?

Answer 1

the answer is 8π radians

Answer 2

Answer:

The angle the minute hand travels in 4 full rotations is $8\ pi\ radians$

Step-by-step explanation:

We know that one complete rotation is given by :

$1\ rotation=1\ hour$

and $1\ hour=60\ minutes=2\ \pi$    

So, $1\ rotation=2\ \pi$

Using unitary method we can find the minute hand travel in 4 rotations.

$\because 1\ rotation=2\ \pi\ radians$

So,  $4\ rotation=8\ \pi\ radians$

Hence, this is the required solution.
