Actually, this has little to do with mathematics and geometry but has to do more with logical reasoning. You have two clauses to get a conclusion from. The reasoning is as follows:
Clause 1: <span>Three noncollinear points determine a plane
Clause 2: </span><span>Points S, O, N are noncollinear
</span>Conclusion: Therefore, points S, O and N form a plane.
Answer: 
Step-by-step explanation:
The circular oil slick is expanding at a rate of 
Let A be the area of the circular oil slick,
So, the changes in A with respect to time (t),
Also, the change in diameter with respect to time(t),
For r = 1.5 m,
![\frac{d}{dt} ( 2 r)]_{r=1.5} = \frac{2}{\pi \times 1.5}=\frac{20}{\pi \times 15}=\frac{4\pi }{3}\text{ meter per hour}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdt%7D%20%28%202%20r%29%5D_%7Br%3D1.5%7D%20%3D%20%5Cfrac%7B2%7D%7B%5Cpi%20%5Ctimes%201.5%7D%3D%5Cfrac%7B20%7D%7B%5Cpi%20%5Ctimes%2015%7D%3D%5Cfrac%7B4%5Cpi%20%7D%7B3%7D%5Ctext%7B%20meter%20per%20hour%7D)
