Answer:
D. 25%
Step-by-step explanation:
There are two ways that I do this. Both of them are probably not what your teacher tells you, but hey, I got the right answer.
The first method is to go through the answers and do 14 x .10, 14 x .20, and so on until you get 3.50.
The second method is to do 14/3.5, which equals 4. This means 14 can be broken up into 3.50 four times. So, 3.50 is 1/4 of 14. What is 1/4 of 100%? 25%.
Since the figures are similar, we can establish a rule of three as follows.
We know that the area of the smaller figure is
, and its volume is
. We also know that the area of the larger figure is
; since we don't now its volume, lets represent it with
:
We can conclude that the volume of the larger figure is
; therefore, the correct answer is
a.
