Answer:
The diameter of the model is 14.4 inches.
Step-by-step explanation:
The Diameter of the moon = 2,160 miles
The scale on the model represents 1 in = 150 miles
Let the model represents k inches in 2,160 miles.
So, by the Ratio of Proportionality:
![\frac{1}{150} = \frac{k}{2160}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B150%7D%20%20%20%3D%20%5Cfrac%7Bk%7D%7B2160%7D)
⇒![k = \frac{2160}{150} \\\implies k = 14.4](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B2160%7D%7B150%7D%20%5C%5C%5Cimplies%20k%20%3D%20%2014.4)
or, k = 14.4 inches
⇒On the scale 2160 miles is represented as 14.4 inches
Hence the diameter of the model is 14.4 inches.
A trapezoid falls under the definition.
