That is actually easier thatn it looks

here is a tip
write that thing apart since they are all multiplication like this:
V=(1/3)pir^2 h
now just divide the whole equaiton by ((1/3)pir^2)
or if you don't like dividiing by fracitons, times both sides by 3/1 to clear fraction to get
3V=pir^2h
divide both sides by pir^2
(3v)/(pir^2)=h

How can you show that two objects are proportional with a table?

vredina [299]

So this is our table:

-----------------
x-values | a b c d e f |
-----------------
y-values | g h i j k l |
-----------------

You can know that the values in the table are proportional if:

$\frac{a}{g}=\frac{b}{h} =\frac{c}{i}=\frac{d}{j}=\frac{e}{k}=\frac{f}{l}$

Hope that helps :)
