Z varies directly with X squared and inversely with Y. When X equals two and Y equals four, Z equals three. What is the value of

gayaneshka [121]

Answer:

Step-by-step explanation:

Set up the equation

z = $\frac{kx^2}{y}$

Plug in the numbers to find the value of k

3 = $\frac{k(2^2)}{4}$

12 = 4k

3 = k

Solve to find the value of z

z = $\frac{3(4^2)}{9}$

z = $\frac{3(16)}{9}$

z = 48/9

z = 16/3

Find the circumference of a circle with an area of 113.1 in square

nlexa [21]

Step-by-step explanation:

$Circumference = 2r\pi \\Area = r^2\pi$

In order for us to find the circumference, we need to find the radius from the given area by rearranging the area formula.

$r=\sqrt{\frac{A}{\pi } }$

$r=\sqrt{\frac{113.1}{\pi } }$

$r=\sqrt{36}$

$r=6$

Now that we have the radius, we can find the circumference.

$Circumference=2(6)\pi$

$Circumference=12\pi$

$Circumference=37.68$

So, when given 113.1 in sq for the area, the circumference of the circle is 37.68 in.
