RSB [31]

Answer:

$72\pi\ in^{3}$

Step-by-step explanation:

step 1

<em>Calculate the volume of the cylinder (flower vase)</em>

The volume is equal to

$V=\pi r^{2}h$

we have

$r=6/2=3\ in$ -----> the radius is half the diameter

$h=12\ in$

substitute the values

$V=\pi (3)^{2}(12)=108\pi\ in^{3}$ ------> exact value

step 2

Calculate 2/3 of the volume

$V=(2/3)108\pi=72\pi\ in^{3}$

Answer:

Y=-2x

When x= -6 then y =12

Step-by-step explanation:

If y and x in direct variation then y=c*x for some constant c.

We are told

-4=c2

——> c= -2

So y= -2x

When x= -6 this becomes

Y= (-2) * (-6)

——> y = 12
