Homework Help: Checking Answer

  1. Sep 15, 2006 #1
    Hi, I had a question that wanted me to find the instantaneous rate of change of V with respect to h for h = 0.60cm. The equation was V = 1/6*pi*h^3 + 2.00*pi*h and I retrieved an answer of 6.85 cm/s. Could anyone tell me if that is correct? Thanks.

    The derivative of V with respect to h and then plug in .6 cm...........

    looks correct to me

    To two decimal places, yes. In future it would be better to show your work rather than just the answer.
