Answer: The angle through which the pendulum travels = .
Step-by-step explanation:
Formula: Length of arc: , where r= radius ( in radians) ,
= central angle.
Given: Length of pendulum (radius) = 45 cm
Length of arc= 27.5 cm
Put these values in the formula, we get
In degrees ,
Hence, the angle through which the pendulum travels = .
Answer:
The answer is .
Step-by-step explanation:
Given:
77.5%.
Now, to write as a fraction or mixed number in simplest form.
77.5%
So, we divide by 10 by removing decimal as decimal is at tenth place.
=
So, simplifying it:
Now, we change into mixed fraction:
Therefore, the answer is .
