Let's keep in mind first, what would be the formula that we would even use. But, when finding this in the first place, we would really need to consider why we would have to use this.
So, we would have to use this mainly because by using this of course, all we would practically do is to plug in the numbers, and from there, our answer would come very clear.
The formula:![\left[\begin{array}{ccc}V= \frac{4}{3} \pi r^3\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DV%3D%20%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Cpi%20r%5E3%5Cend%7Barray%7D%5Cright%5D%20)
So, by using this formula, lets then plug in some numbers.

Cos(<span>θ) < 0, so we know it would be in Quadrant 2 or 3

Answer:
P = 1/(sqrt(4)) and w = 1/(sqrt(9))
Step-by-step explanation:
Only the roots of perfect squares are rational numbers. 2, 3, 6, and 10 are not perfect squares, so their roots are irrational. Both 4 and 9 are perfect squares, so their roots are rational. The sum of rational numbers is a rational number.
