To determine the scale factor for enlarging a rectangle from 8 cm x 10 cm to 16 cm x 20 cm, divide the dimensions of the larger rectangle by the dimensions of the smaller rectangle. For the width, 16 cm ÷ 8 cm = 2, and for the height, 20 cm ÷ 10 cm = 2. Therefore, the scale factor you would use is 2.
To determine the radius of the larger cylinder, we need to know the radius of the smaller cylinder and the scale factor between the two cylinders. If the scale factor is provided, multiply the radius of the smaller cylinder by this factor to find the radius of the larger cylinder. Without specific measurements or a scale factor, we cannot calculate the radius of the larger cylinder.
The scale factor between two similar shapes is the ratio of the dimensions of one (often the smaller) compared with the dimension of the other (the larger).
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.

The two scale factors are reciprocals of one another.
To determine the scale factor for enlarging a rectangle from 8 cm x 10 cm to 16 cm x 20 cm, divide the dimensions of the larger rectangle by the dimensions of the smaller rectangle. For the width, 16 cm ÷ 8 cm = 2, and for the height, 20 cm ÷ 10 cm = 2. Therefore, the scale factor you would use is 2.
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.

Assuming the smaller sphere is the image of the larger sphere after transformation (based on the order of the radii): the scale factor is 4/12 = 1/3
100 is the scale factor

To find the scale factor, you need to compare the corresponding sides of two similar figures. The scale factor is calculated by dividing the length of a side on the larger figure by the length of the corresponding side on the smaller figure. For example, if the larger figure has a side length of 8 units and the corresponding side on the smaller figure is 2 units, the scale factor would be 8 divided by 2, which equals 4.

If you know one of the sides of both the rectangles than you just divide them by one another to find the scale factor.
