3. Suppose R is the region in the plane bounded below by the curve y = x² and above by the line y = 1. a) Sketch R. Set up and evaluate an integral that gives the area of R. b) Suppose a solid has base R and the cross-sections of the solid perpendicular to the y-axis are squares. Sketch the solid and find its volume. c) Suppose a solid has base R and the cross-sections of the solid perpendicular to the y-axis are equilateral triangles. Sketch the solid and find its volume.
