6. Consider the region R that is the area between the graphs of y = x and y = $2. A solid is formed using R as its base and crossrsection slices perpendicular to the mraxis are equilateral triangles. Find the volume of this solid. 7. Sketch the region bounded by y + m : 6, y : 0 and m : 0. Use the disk method to nd the volume of the solid of revolution formed When this region is rotated around the :rraxis. 8. Sketch the region bounded by y : 3:52, 1" : 05 a: : 2, and y : 0. Use the disk method to nd the volume of the solid of revolution formed when this region is rotated around the maxis
