my teacher never actually went over this, but i tried doing them anyway. there were 15 problems originally assigned, and i wanted to get them all done on my own before class on tuesday, im hoping you guys can help out(adsbygoogle = window.adsbygoogle || []).push({});

12) You want to make a pyramid with height = 3260 and square base with side s=1780

a) find the integrand

b) find the volume

i know the volume of a pyramid is Bh/3, but i dunno how to get the area of the delta x and then sum infinite delta x's together

14) Find the volume of the solid formed by rotating the region enclosed by:

y= e^(4x) + 1

y = 0

x = 0

x = 0.5

15) find for the volume of the solid formed by rotating the region inside the first quadrant enclosed by

y=x^3

y=25x

do i go about finding the volume of the entire solid if i were to rotate it around and then cut it in half?

thanks a ton guys, i usually get great hw from this forum
