The end of a pendulum with a length of 21 cm travels an arc length of 24 cm. how many degrees does the pendulum swing?

It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.

So here radius is 21 cm and the arc length is 24 cm .

Now we use the arc length formula , which is

Where s is the arc length and r is the radius.

Substituting these values, we will get

And now we need to convert radian to degree, and for that we have to multiply by

That is

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
