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

Answer:
6 whole packages as the other half can't be count
Step-by-step explanation:
Answer:
We need more information than that.
Step-by-step explanation:
ANSWER
Scale factor is 1.25
The dilation is an enlargement.
EXPLANATION
Let the scale factor of the dilation be k, then

We divide both sides by 5 to get,

This implies that,

Since the scale factor is more than one, the dilation is an enlargement.
