Find the volume of the following solids. The base of a solid is the region between the curve y = 12√/sin x and the interval [0,л] on the x-axis. The cross-sections perpendicular to the x-axis are a. equilateral triangles with bases running from the x-axis to the curve as shown in the figure. b. squares with bases running from the x-axis to the curve.
