It will take 0.556 seconds for an echo to reach one's ears
<h3>Calculating the time to hear an echo</h3>
From the question, we are to determine how long it would take an echo to reach one's ears
From the formula,
NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance
From the given information,
Distance = 92.0 m
NOTE: Speed of sound in air at 0 °C ≅ 331 m/s
Putting the parameters into the formula, we get
Time = 0.556 secs
Hence, it will take 0.556 seconds for an echo to reach one's ears.

Answer:
Volume of cylinder is 953.77 cm³ and volume in term of π is 303.75π
Step-by-step explanation:
Given: Diameter is 9 cm
Height is 15 cm.
First lets find out the radius of cylinder.
As given, diameter is 9 cm
we know, radius= 
Radius= 
Now, finding the volume of the cylinder.
Formula; Volume of cylinder= 
where r is radius and h is height of cylinder.
⇒ Volume of cylinder= 
⇒Volume of cylinder= 
⇒Volume of cylinder= 
Taking π = 3.14
⇒ Volume of cylinder= 
⇒ Volume of cylinder= 953.77 cm³
Hence, volume of cylinder is 953.77 cm³ and volume in term of π is 303.75π.
It snowed 57.5 in Big Bear
Because 15% of 50 is 7.5 and 50+7.5=57.5
