    I assume you've done part (a)?
    If so, you should be able to relate (b) to (a) - if not, reread the question, and think about the similarities and differences between the candle and the solid generated in part (a). You should see a relationship between the 2 solids

    I think part a and b is exactly the same thing except they gave AB =15 and in part A they gave -1 and 2/3
    so what i have done so far is that i used the expression that I got in part a but replace it limits with 0 and 15 but I get the wrong answer

    I'm thinking volume scale factor = linear scale factor cubed.

    The original length would be 1+2/3 = 5/3. The new is 15. The linear scale factor = 9 so the volume will be 729x bigger.

    Changing the limits will give you a different shape. You have the right idea in terms of the relationship between the 2 shapes, but you need to use a scale factor instead of changing the limits (remember volume scale factor != linear scale factor)

    The height of the generator solid is \frac{5}{3} units, let's say these units are cm, then to go from this height to 15cm you need to multiply by 9. Hence 9 is your linear scale factor, use it for the candle volume.
