Answer:
Option B.
Step-by-step explanation:
Let the radius of the snare drum = r
and radius of the model = R
Ratio of the dimensions of the snare drum and the model = 1 : 4
So, ![\frac{r}{R}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Br%7D%7BR%7D%3D%5Cfrac%7B1%7D%7B4%7D)
Now as per question, dimensions of the snare drum is multiplied by a scale factor of ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Radius of the snare drum = ![\frac{r}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Br%7D%7B2%7D)
Ratio of the radius of the snare drum and cylindrical model ,
![\frac{\frac{r}{2}}{R} =\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7Br%7D%7B2%7D%7D%7BR%7D%20%3D%5Cfrac%7B1%7D%7B4%7D)
![\frac{r}{2R}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Br%7D%7B2R%7D%3D%5Cfrac%7B1%7D%7B4%7D)
![\frac{r}{R}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Br%7D%7BR%7D%3D%5Cfrac%7B1%7D%7B2%7D)
Therefore, the cylinder with Sara's dimensions will be geometrically similar but the scale factor will be 1 : 2
Option B is the answer.
Based on the information given, the bisected angle, quadrilateral, and congruent angles will be explained.
<h3>How to illustrate the information?</h3>
It should be noted that a quadrilateral simply means a closed shape that has four sides and four angles. These include square, rectangle, parallelogram, etc.
A bisected angle simply illustrates a line that splits an angle onto two equal angles.
Congruent segments are the segments that have the same length.
The diagrams are attached accordingly.

Answer: RQS= 90, QRS= 43, QSR= 47
Solving Steps:
180-90=90 (all the angles combined equal 180)
9x-2+10x-3=90
19x-5=90
19x=90+5
19x=95
x=5
9(5)-2= 43
10(5)-3= 47
