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 multiples 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 if it was written as 1/4.

    Because she multiplied the dimensions by 1/2, that would be a ratio of 1:2

    The answer is:

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