set up an integral equation that will find the volume of a solid whose base is bounded by the graphs of y = 7x^2 - 11x and y = 0, with cross sections of squares taken perpendicular to the x axis. thank you!! :)

    i think it's the intersections, which are at x= 0 and 11/7

    \[\int\limits_{0}^{11/7} (7x ^{2} - 11x) dx\]

    wait before the integral sign, there need to be pi & the equation under the integral needs to be squared

    I think the the factor should be squared

    okay thanks! but i don't understand the pi before the integral, isn't that only for disks and washers and whatnot?
