Answer:
The answer is B. His slope should be positive because the trend line is slanted up to the right.
Step-by-step explanation:
This answer is correct because the thred line is slanted up to the right, so it makes it positive. "His slope should be positive because the coordinates of all the plotted points are positive." is wrong because all the coordinates plotted positive isn't a valid reason. The other answers are wrong because the slope is positive.
Given a radius 
, the volume of a sphere is given by
We can solve this formula for the radius, given the volume:
![r=\sqrt[3]{\dfrac{3V}{4\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B3V%7D%7B4%5Cpi%7D%7D)
We can plug our value for the volume to get the radius:
![r=\sqrt[3]{\dfrac{3\cdot 12\pi}{4\pi}}=\sqrt[3]{9}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B3%5Ccdot%2012%5Cpi%7D%7B4%5Cpi%7D%7D%3D%5Csqrt%5B3%5D%7B9%7D)
