v=1/3pie r sqaured h make h the subject

I would like some help on this question

$V = \frac13 \pi r^2 h$

Multiply both sides by 3:

$V\times 3 = \frac13 \pi r^2 h \times 3$

$3V = \pi r^2 h$

Divide by pi on both sides:

$\frac{3V}{\pi} = r^2 h$

Divide by r^2 on both sides:

$\frac{3V}{\pi r^2} =h$

$h = \frac{3V}{\pi r^2}$

Remember that once to try to remove something from one side, be sure to do the same thing on the other side. :)

The main thing is, never spell ${\pi}$ as 'Pie'. It's Pi

This is a Greek letter, not a pastry.

If only it was a pastry, more students would be interested in it:p.

I've also heard that the pronunciation is "pee" not "pie" for $\pi$ , sine we say "phee" not "fie" for $\phi$

We have people already confusing it with pastry, let alone if we were to pronounce it pee. :D

(Of course, this does come in handy if you're actually making a pie, which would be round.)
