Sara is a drummer in her school is marching band she wants to make a geometrically similar model of a snare drum for her stuffed animals. To find the dimensions she should use to make a cylindrical model with a scale of 1 : 4, Sara measures the radius and height of a snare drum and multiplies each dimension by 1/2. Which statement is true? A. A cylinder with Sara’s dimensions will be geometrically similar, and the scale factor will be 1:4

B. A cylinder with Sara’s dimensions will be geometrically similar, but the scale factor will be 1:2

C. A cylinder with Sara’s dimensions will be geometrically similar, but the scale factor will be 1:8

D. A cylinder with Sara’s dimensions will not be geometrically similar

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,

Now as per question, dimensions of the snare drum is multiplied by a scale factor of

Radius of the snare drum =

Ratio of the radius of the snare drum and cylindrical model ,

Therefore, the cylinder with Sara's dimensions will be geometrically similar but the scale factor will be 1 : 2

Option B is the answer.

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

yes. we do proportions in probabilities.
