Solve for r v = 4/3 r^3

sergejj [24]

Answer:

$r=\sqrt[3]{\frac{3v}{4} }$

Step-by-step explanation:

To solve for $r$ :

$v=\frac{4}{3}r^{3}$ (given)

$\frac{3v}{4}=r^{3}$ (times $\frac{3}{4}$ on both sides)

$r=\sqrt[3]{\frac{3v}{4} }$

I hope this helps :)

Ys is the perpendicular bisector of xz. What is the length of Xs if xz is 18 inches long?

exis [7]

Answer:

XS is 9 inches long.

Step-by-step explanation:

Given that

YS is the perpendicular bisector of XZ.

Length of XZ = 18 inches

To find:

Length of XS = ?

Solution:

First of all, let us learn about the perpendicular bisector.

Perpendicular bisector of a line AB is a line PQ, which divides the line AB in two equal parts and is at an angle of $90^\circ$ with the line AB.

If B is on the line PQ, then $BP = BQ = \frac{PQ}{2}$ and

$\angle ABP = \angle ABQ = 90^\circ$

Applying the above property in our given question.

Kindly refer to the attached image for the given dimensions.

S is on the line XZ.

$XS = SZ = \frac{XY}{2} = \dfrac{18}{2} \\\Rightarrow \bold{XS = 9\ inches}$

So, the answer is XS is 9 inches long.
