V = (pi)(r^2)(h)

h = V/[(pi)(r^2)]

h = (271.4)/[(pi)(6^2)]

anonymous · Answer

Can you do the arithmetic from this point or do you still need help?

erinweeks · Answer

i got 30694.61 but that doesnt sound right to me..

anonymous · Answer

I'll help you a bit further:

h = (271.4)/[(pi)(6^2)]     =      (271.4)/[(3.14)(36)]      =     2.4

anonymous · Answer

All good now?

erinweeks · Answer

i dont get how you got the 2.4 though :/

anonymous · Answer

In words, it's    271.4 divided by the product of 36 and 3.14

You multiply 36 by 3.14 and get a number.  You divide 271.4 by that number.  That's all there is to it.
