The region R in the first quadrant is bounded by y = 5 sin 5 sin (5+), y = 5(x - 2) and y = 4x + 1, and contains the point (2,5). The area of Ris: area The volume of the solid generated by rotating R about the -axis is: volume The volume of the solid generated by rotating R about the y-axis is: volume The volume of the solid with R as its base and square cross-sections perpendicular to the 2-axis (and to the ry.plane) is: volume
