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
It is: 21/12 = 7/4

Multiply each dimension by the scale factor:9 x 12 → (9 x 2.5) x (12 x 2.5) = 22.5 x 30
The area scale factor is the square of the side length scale factor.
Tautologically!
You increase the scale factor.
To find the scale factor, you need to convert both measurements to the same unit. Since 8 feet equals 96 inches (1 foot = 12 inches), the scale can be expressed as 4 inches equals 96 inches. The scale factor is then calculated by dividing the two measurements: 96 inches / 4 inches = 24. Therefore, the scale factor is 24:1.
