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!! :)

Question

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!! :)

anonymous · Answer

do you know what the boundaries are?

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

I think the the factor should be squared

anonymous · Answer

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

anonymous · Answer

there should not be pi

anonymous · Answer

OHHH! got it. thank you all (:
