The base of a certain solid is the triangle with vertices (0,0), (2,0), and (0,4). Cross-sections perpendicular to the y-axis are isosceles triangles with height equal to the base. Use the formula V = SA(y) dy to find the volume of the solid. The lower limit of integration is a = The upper limit of integration is b = The base of the triangular cross-section is the following function of y: The area of the triangular cross-section is A(y)= Thus the volume of the solid is V =
