Please help NO LINKS A volume is described as follows:
1. the base is the region bounded by
y
=
4
−
4
25
x
2
and
y
=
0

2. every cross section parallel to the x-axis is a triangle whose height and base are equal.

Find the volume of this object.

volume =

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
