1, Find the volume of the solid obtained by rotating the
region bounded by
y=6x^2, x=1, and y=0, about the x-axis.
V= ?
2, Find the volume of the solid obtained by rotating the
region bounded by y=x^2 , y=0,
and x=4, about the y-axis.
V=?
3, Find the volume of the solid formed by rotating the
region enclosed by
y=e^4x+5, y=0, x=0, x=0.8
about the x-axis.
4, A volume is described as follows:
(1.) the base is the region bounded by y=9−9/16 x^2
and y=0
(2). every cross section perpendicular to the y-axis is a
triangle whose height and base are equal.
