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
