Arc Length and Volume of Solids (Need Help QUickly!)

  1. Mar 3, 2006 #1
    i have 2 calculus questions that are due in the next half n hour and i have no idea how to even start them. I hope somoene can help me in time.

    Question1
    Find the volume of the solid obtained if the plane region E bounded by the curve y=x^2 and y=x^3 between x=0 and x=1 is rotated about the x-axis

    Question2
    Find the length of the curve y=coshx between points (0,1) and (1,e^2+1/2e)

    If anyone can help me...i need the solutions quickly...thanks in advance

    I think you're misunderstanding the purpose of these forums.

    If you truly want to learn the material, forget the homework deadline. You already dug your own grave anyway, by waiting until the last half hour (not that i'm condemning this - we've all been there).

    Instead, work out what you can with the problems, show us what you've gotten so far, and somebody will surely jump in and guide you further.
