Information on the cost of things, quantitative data has to do with numbers, qualitative data uses details such as taste, appearance, what it looks like etc. 

See diagram.we use washers to get the area and we will be integrating with respect to xouter radius is the  distance between y = e^x and y = -1    inner radius of washer is the distance between y = 1 and y = -1    the area of one cross-section of a washer is    solid lies between x = 0 and x = 2. the volume is    if you need this expanded, then    the question doesn't say to evaluate, so we're done.   

Sean is correct and steve is wrong (enunciation is how you say the words). did this ? : 3
