If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.
An example of the equation would be
y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept
You find three times that number.

Step-by-step explanation:
v=1/3nr2h for h
3(v)=3(1/3nr2h)
3v/2nrh=2nrh/2nr
3v/2nrh=h
h = 3v/2nrh
