A. 2.4 in. B. 7.2 in. C. 14.4 D. 4.8 in.

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

4. tcarroll010

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

5. ErinWeeks

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

6. tcarroll010

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

7. tcarroll010

All good now?

8. ErinWeeks

i dont get how you got the 2.4 though :/

9. tcarroll010

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.
