I need to double check: where is the h? On the 'ground' with r, or in the exponent with 2?
OpenStudy (anonymous):
on the ground, r is being squared
OpenStudy (anonymous):
Awesome.
so to make it look nicer, we'll write it as: pi*h*r^2
OpenStudy (anonymous):
okay that looks better
OpenStudy (anonymous):
Actually, come to think of it, we need to know something... did they say the equation = 0? Because we can't solve it without an equal sign.

no its v=pi*h*r^2 for h?
OpenStudy (anonymous):
Ah, ok. We've gotta have that v to solve this. :P
OpenStudy (anonymous):
What we want to do is try to get the h by itself. So how do you get pi to go away?
OpenStudy (anonymous):
I must go in a couple of minutes, so lemme know soon!
OpenStudy (anonymous):
divide both sides?

by pi?
OpenStudy (anonymous):
Yup! So what do we get?
OpenStudy (anonymous):
v/pi= r^2*h
OpenStudy (anonymous):
perfect! Now what else is 'bothering' our h?
OpenStudy (anonymous):
the r^2

And how do we make the r^2 go to the other side?
OpenStudy (anonymous):
square root?or divide?
OpenStudy (anonymous):
what kinda math is this?
OpenStudy (anonymous):
divide, same as the pi

@arboring:
Looks like physics and algebra.

so the answer is v/pi*r^2=h?
OpenStudy (anonymous):
That's right!
OpenStudy (anonymous):
thanks

No prob.
