In a cinema theatre, why do we normally not hear echoes even though the sounds are loud?

Answer:

An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being produced the echo has to be absorbed. Echo in a cinema theatre is absorbed by the WALLS of the theatre.

They are not plain. The walls are corrugated or shaped to form tiny holes or empty spaces to ABSORB the ECHO. Modern Theatre's have ABSORBENT materials sticked to the walls of the theatre.

A cube has an edge of 2 feet. The edge is increasing at the rate of 5 feet per minute. Express the volume of the cube as a funct

Agata [3.3K]

Answer:

$V(m) = (2 + 5m)^3$

Step-by-step explanation:

Given

Solid Shape = Cube

Edge = 2 feet

Increment = 5 feet per minute

Required

Determine volume as a function of minute

From the question, we have that the edge of the cube increases in a minute by 5 feet

<em>This implies that,the edge will increase by 5m feet in m minutes;</em>

Hence,

$New\ Edge = 2 + 5m$

Volume of a cube is calculated as thus;

$Volume = Edge^3$

Substitute 2 + 5m for Edge

$Volume = (2 + 5m)^3$

Represent Volume as a function of m

$V(m) = (2 + 5m)^3$

A gardener wants to replant a circular bare spot in a yard with grass. The bare spot has a radius of 8 inches. What is the area

ch4aika [34]

The area of the bare spot the gardener needs to replant is 201 square feet

Step-by-step explanation:

We have to find the area of the circular bare spot

Given

Radius of bare spot = r = 8 inches

The formula for area of a circle is given by:

$Area=A = \pi r^2$

putting the value

$A = 3.14 * (8)^2\\= 3.14 * 64\\=200.96$

Rounding off to nearest foot

201 ft^2

Hence,

The area of the bare spot the gardener needs to replant is 201 square feet

Keywords: Area, radius
