I have a flower vase with a 6 " diameter and is 12 " tall I want to fill it 2/3 of the way full how many cubic inches will I fil

garik1379 [7]

Answer:

$72\pi\ in^{3}$

Step-by-step explanation:

step 1

Calculate the volume of the cylinder (flower vase)

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

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

1/x + 1/4 = 7/12 solve for x

Licemer1 [7]

Given equation is
$\frac{1}{x} + \frac{1}{4} = \frac{7}{12}$

We can solve it by subtracting 1/4 both side
$\frac{1}{x} + \frac{1}{4} - \frac{1}{4} = \frac{7}{12} - \frac{1}{4}$

$\frac{1}{x} = \frac{7}{12} - \frac{1}{4}$
                          $= \frac{7 - 3}{12}$
                          $= \frac{4}{12}$
                          $= \frac{1}{3}$

So $\frac{1}{x} = \frac{1}{3}$
On comparing x = 3.

SO the solution of equation is x = 3

1. 2X + 1 = Y<br> 2Y = 6<br> Show your work

slamgirl [31]

Answer:

x = 1

y = 3

Step-by-step explanation:

2x + 1 = y ------- eqn (1)

2y = 6--------eqn (2)

from eqn(2)

2y = 6

y = 3

when you divide 6 by 2y

substitute y = 3 into eqn (1)

2x + 1 = y

2x + 1 = 3

2x = 3-1

2x = 2

therefore

x = 1
