The correct answer is:  [C]:  " 37, 680 mm³ " .
________________________________________________________

Explanation:
________________________________________________________

The formula for the volume, "V" , of a cylinder is:

                →   V  =   \pi  *  r²  *  h  ;  

                           → in which "r = length of radius" ;  "h = height" ;             ________________________________________________________

     {Note that the formula for the volume, "V" , of a cylinder is:
     
                              →   " Base area * height " .
________________________________________________________

         →  Specifically, for a cylinder, the "Base area" is the area of a "circle", because the base is a circle;  

          →  and the formula for the "area of a circle = [tex] \pi [/tex] * r² " ;

          →  in which "r = length of the radius" . 

As such, the formula for the volume, "V" ,  of a cylinder is:
______________________________________________________
       →   Volume  =  (Base area) * (height) ; 

                             =  ( \pi r² ) * h  ;
______________________________________________________

       →   V  =  \pi  r²  h  
; 

                 in which:  "V = volume  {in "cubic units" ;  or, write as " units³ " } ;

                                  "r = radius length" ; 

                                  "h = height" ;
_____________________________________________________
  →  Now, we shall solve for the volume, "V", of the given cylinder in this question/problem:
_____________________________________________________

          →   V  = \pi  r²  h  ; 

                      in which: "r = radius = ? "  ; 

                        →  To find "r" ;  We are given the diameter, "d = 40 mm" ; 
 
                        →  Note that:  "r = d/2 = (40 mm) / 2 = 20 mm " ; 

                              {i.e., "the radius is half of the diameter".}.  

                        →  " r = 20 mm " ;  

                        →  " h = height = 30 mm " {given in figure) ; 
      
                        →  For \pi ; let us use " 3.14 " — which is a commonly used approximation.  

             →  For this question/problem, none of the answer choices are given "in terms of \pi " ;
     →   so we shall use this "numerical value" as an "approximation" ; 
_______________________________________________________

Now, let us plug in our known values into the formula;
     and calculate to find the volume, "V", of our given cylinder; as follows:
_______________________________________________________

    →    V  = \pi  r²  h  ; 

                =  (3.14) * (20 mm)²  * (30 mm) ; 

                =  (3.14) * (20)² *  (mm)²  * (30 mm) ;
          
                =  (3.14) * (20)² * (30) * (mm³) ;

                =  (3.14) * (400) * (30) * (mm³) ; 

                =  37, 680 mm³
__________________________________________________

The volume is
:  " 37, 680 mm³  " ;  

          →  which is:  Answer choice  [C]:  " 37, 680 mm³ " .

Ammar is constructing an angle congruent to ∠MNP . With his straightedge, he draws and labels DE−→− . He places the compass poin
Svetlanka [38]

Ammar's next step is point C

<h3>Further explanation </h3>

Angles can be formed from two ray lines that have the same starting point

Commonly used terms include foot angle, corner point, and angle size

The magnitude of the angle is usually expressed in degrees

Naming angles can be with one letter according to the vertex or with three letters with the vertex placed between two other letters

There are several steps used to copy the MNP angle:

1. Draw the DE line

2.Places the compass point on point N and draws an arc that intersects NM (point Q) and NP (Point R)

3.Without changing the compass opening, put the compass point on point D and draw a long arc that intersects DE (point F)

4. Open the compass so that the compass point is on point Q and the pencil point is on point R. Then put the compass point on point F and draw an arc (intersect with the arc in step 3, and at this point we name it G)

5. Draw a line from point D to point G

Then the MNP is congruent to the EDG

WILL AWARD BRAINLIEST!!!
Anna007 [38]

Answer:

<u>A. p(hat) = .139</u>

We divide our sample population by the amount who tested positive. 14851/107109 = .139.

<u>B. 1.62 million</u>

We just multiply the p times the population. 11.69 M * .139 = 1.62 M

<u>C. No</u>

It depends upon the sample method. From what I can tell, I assume all conditions are met and it was not biased.

If it wasn't random, that is a problem, but we aren't given this information.

We can test if it's small enough. It can't be larger than 10% of the population. 107109 * 10 < 11.69 million, so it's small enough.

We can also test if it's large enough. np and nq must be greater than 10. 107100 * .139 > 10, 107100 * .861 > 10.
