    Rectangle volume using cross sections

    Ok so we will be integrating between x=0 and x=3. This is due to the region being bound by x=3 and y=x^2 (where y=0 @ x=0). Therefore, V = (0∫3)* (x^2)(0.5(x^2)) dx height (1/2b)-----------------^ base------------------^ -----------------^upper and lower limit of...
