V = 1/3 π r² h
3V = 3(1/3) π r² h
3V / π r² = π r² h / π r²
3V / π r² = h

Okay. Since you are multiplying everything on the right side of the equation, and the left side is just one variable. To solve for h you just divide each side by 1/3Ïr².
So, here's the original equation:
V=1/3Ïr²h
Now let's divide both sides of the equation by 1/3Ïr², since what you do to one side of the equation you do to the other. We get:
V/(1/3Ïr²)=(1/3Ïr²h)/(1/3Ïr²)
Then, obviously, on the right side of the equation the 1/3Ïr² term cancels out. Now we have:
h=V/(1/3Ïr²)
Now it's not a good idea to leave a fraction in the denominator, so now we should multiply both sides of the fraction by 3.
(V*3)/(1/3Ïr²*3)
In the denominator everything is multiplied, and since multiplication is cumulative, we can simplify it by multiplying the two constants, 1/3 and 3, which is 1, and since one multiplied by anything equals 1, it would be Ïr² on the bottom.
So,
h=3V/Ïr²
Therefore, the value of h is:
3V

Ïr²
There you go. I'm glad I could help. :)
