Answer: A cylinder with Sara’s dimensions will be geometrically similar, but the scale factor will be 1:2
Explanation:
Here is the complete question:
Sara is a drummer in her school’s 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 cylinder model with a scale of 1:4, Sara measures the radius and height of a snare drum and multiplies each dimensions by 1/2, which statement is true?
A. a cylinder with Sara’s dimensions will be geometrically similar, and 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
The ratio 1:4 would be the same as when it was written asa fraction as 1/4. Then, she multiplied the dimensions by 1/2, this would be a ratio of 1:2
Then the answer is that a cylinder with Sara’s dimensions will be geometrically similar, and the scale factor will be 1:2
