5) Use the general (cross-sectional) slicing method to find the volume of the following solid. a) The solid whose base is the region bounded by the curves y = x and y =2-x , and whose cross- sections through the solid perpendicular to the x-axis are semi-circles. ETTT V= b) The base of a solid is the semi-circular region bounded by the curves x = \4- y and x = 0. Each cross-section perpendicular to the y-axis is a right-isosceles triangle with the right angle leg lying parallel to the x-axis (perpendicular to the y-axis). Set up the integral to find the volume of this solid. V =
