1) The scale factor is 0.25 is true.
Step-by-step explanation:
Step 1:
The first figure is dilated to form the second figure. The shape is a rhombus.
It is given that the side length of the first figure is 5.8 and the side length of the second figure is 1.45.
Step 2:
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the side length of the rhombus.
The scale factor
So the scale factor is 0.25. This is the first option.
Answer:
91.3 in³
Step-by-step explanation:
The formula for the volume of a pyramid is:
V = where B=area of the base and h=height of the pyramid
Given the dimensions in the problem and that the pyramid has a square base, we can first calculate the area of the base:
A = 7.4 x 7.4 = 54.76 in²
Multiply the area of the base x height of the pyramid: (54.76 x 5) = 273.8
Divide by 3 (multiply by ): 273.8/3 ≈ 91.3 in³
