<h2>○=> <u>Correct option</u> :</h2><h2>
![\color{plum}\tt\bold{(B)}](https://tex.z-dn.net/?f=%5Ccolor%7Bplum%7D%5Ctt%5Cbold%7B%28B%29%7D)
</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>
We know that :
![\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r](https://tex.z-dn.net/?f=%5Ccolor%7Bhotpink%7D%20%5Ctt%20%5C%3A%20circumference%20%5C%3A%20of%20%5C%3A%20a%20%5C%3A%20circle%5Ccolor%7Bplum%7D%20%3D%202%5Cpi%20r)
So, let the diameter of this circle be x.
Which means :
![=\tt2 \times \pi \times r](https://tex.z-dn.net/?f=%20%3D%5Ctt2%20%20%5Ctimes%20%5Cpi%20%20%5Ctimes%20r)
![=\tt 2 \times x \times \pi = 12\pi](https://tex.z-dn.net/?f=%20%3D%5Ctt%202%20%5Ctimes%20x%20%5Ctimes%20%5Cpi%20%3D%2012%5Cpi)
![=\tt 2x\pi = 12\pi](https://tex.z-dn.net/?f=%20%3D%5Ctt%202x%5Cpi%20%3D%2012%5Cpi)
![=\tt x = \frac{12}{2}](https://tex.z-dn.net/?f=%20%3D%5Ctt%20x%20%3D%20%20%5Cfrac%7B12%7D%7B2%7D%20)
![= \tt \: x = 6 \: m](https://tex.z-dn.net/?f=%20%3D%20%5Ctt%20%5C%3A%20x%20%3D%206%20%5C%3A%20m)
Thus, the radius of the circle Robert drew = 6 m
Since the circle in option B has a radius of 6 m, it is the circle Robert drew.
▪︎<em>Therefore, the correct option is (B)</em>
D because you need to make the denominators have a common multiple.

Answer:
D) (x, y) → (1/3x , 1/3 y)
Step-by-step explanation:
A dilation is a change of size, if the dilation factor is greater than 1, then the figure is enlarged. If the dilation factor is smaller than 1, the figure is shrinked. In both cases, the coordinates are MULTIPLIED by the dilation factor.
Among the 4 choices, only 2 are dilations. One is with a dilation factor of 3 (A), which means the shape was enlarged. And the other is with dilation factor of 1/3, meaning the shape was shrinked.
Since we went from MNOP (LARGE one) to M'N'O'P' (small one), the dilation factor was < 1... so 1/3 is the answer.
Answers B and C show a translation/movement of the shape, not a dilation.
