Q: A solid has a base in the form of the ellipse: x^2/25 + y^2/16 = 1. Find the volume if every cross section perpendicular to the x-axis is an isosceles triangle whose altitude is 6 inches.(adsbygoogle = window.adsbygoogle || []).push({});

I got 11.781 (or 3.75pi) but I just wanted to check my answer.

Q: Use the same base and cross sections as #3, but change the axis to the y-axis.

Here I got 7.54 (or 2.4pi)
