Practice: Find the volume of the solids with the following descriptions: a. Set up the integral representing the volume V of the solid whose base is the region enclosed by the parabola y = 2 – x² and the x-axis. Cross-sections perpendicular to the -axis are semicircles. b. Evaluate the volume V of the solid whose base is an equilateral triangle with sides 7. With Cross- sections perpendicular to the x-axis are right isosceles triangles.
