Answer:
104.72 m^2.
Step-by-step explanation
I'm taking the angle to be 30 degrees.
Area of sector = area of the circle * 30/360
= pi*20^2 * 30/360
= 400pi * 1/12
= 104.72 m^2.

The wave length of the sound with parameters frequency of 125 Hz and a speed 5000 m/s is 40 meters
<h3>Given Data</h3>
velocity = 5000 m/s
frequency = 125 Hz
wavelength = ??
We know that the relationship between speed, frequency and wavelength is given as
v = fλ ----------------------------1
substitute our given parameters
5000 = 125 * λ
Divide both sides by 125
λ = 5000/125
λ = 40 m
Hence the wave length of the sound is 40 meters
