Step-by-step explanation:
The square root of 32 is between two integers which are 5 and 6.
5 < < 6
Integers are sets of numbers that are made up of whole numbers;
5 is a perfect square and so is 6;
The square of 5 is 25
The square of 6 is 36
Since 32 is closer to 36, we can expect the square root of 32 to be greater than the mid point between 5 and 6 i.e > 5.5

Answer:
Approximately the volume of cone-shaped container is <u>393 in³</u>.
Step-by-step explanation:
Given:
A company makes a cone-shaped container with a height of 15 in.
The area of its base is about 78.8 in².
Now, to get the cone-shaped container volume.
So, we find the radius first by using formula:
Let the radius be
<u><em>(Using the value π = 3.14)</em></u>
<em>Dividing both sides by 3.14 we get:</em>
<em /><em />
<em>Using square root on both sides we get:</em>
Thus, the radius () = 5 in.
<u>The height (</u><u>) = 15 in.</u>
Now, to get the volume of the cone-shaped container we put formula:
Therefore, approximately the volume of the cone-shaped container is 393 in³.
