Thread: Volumes by Slicing

I've been working on this problem for about half an hour and haven't gotten anywhere.

The base of a solid is the region between the curve y=2sqrt[sinx] and the interval [0, pi] on the x-axis. The cross-sections perpendicular to the x-axis are equilateral triangles with bases running from the x-axis to the curve.

I think I'm supposed to use the formula V=A(x)dx, need help, thanks.

area of an equilateral triangle with side length is





set it up and find the volume.
