## anonymous 5 years ago 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!! :)

1. anonymous

do you know what the boundaries are?

2. anonymous

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

3. anonymous

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

4. anonymous

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

5. anonymous

I think the the factor should be squared

6. anonymous

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

7. anonymous

there should not be pi

8. anonymous

OHHH! got it. thank you all (:
