Answer:
![c = \pi d](https://tex.z-dn.net/?f=c%20%3D%20%5Cpi%20d)
circumference = pi * diameter
Answer:
6
Step-by-step explanation:
5y+9=39
-9 on both sides to get the y by itself =30
5y=30
now divide 5 on both sides and you get y = 6
Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.
The change of amplitude of a sound wave's amplitude is linked to the change in pressure that occurs due to the wave measured at a given location.
Frequency tells the number of waves that pass a fixed location in a specific time frame.
<h3>How does sound waves relate to trigonometric functions?</h3>
Sound engineers uses the basic laws of trigonometry via sine and cosine graphs.
Note that all sounds can be broken down into a lot of sine waves, as sine waves comes together to form sounds.
Therefore, Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.
