Look at the formula for the volume of a cylinder below.

scZoUnD [109]

$h = V / ( \pi r^2)$

Okay, so we already have the volume equation for a cylinder here.
$V = \pi r^2 h$
Since we need to find the height(h), we need to basically isolate it in the equation. To do that we just have to divide both sides by (pi * r^2), where we end up with:
$V / (\pi r^2) = h(\pi r^2) / (\pi r^2)$
then
$V / ( \pi r^2) = h$
$h = V / ( \pi r^2)$

Y=1/3x-3<br> Y=-x+5 <br> How do I solve

ehidna [41]

Since both equations are equal to y, we can just combine them like this:

1/3x-3=-x+5

1/3x=-x+8

4/3x=8 (since x is 1x which is 3/3x)

x=6

Plug x back in:

y=-6+5

y=-1

So x=6 and y=-1

Hope this helped!

Sheree pours 2 L of water equally into 10cups Each cup can hold 400 mL there is no water left in the bottle how much water is in

mina [271]

2L = 2000mL

2000mL / 400mL = 5
therefore, each cup is filled exactly half way

There is 200mL in each of the 10 cups.
