Set up integrals for both orders of integration. Use the more convenient order to evaluate the integral over the plane region R. y Jਤ 04 R: trapezoid bounded by y = x, y = 8x, x = 1, x = 8 y dx dy + dx dy y dy dx = Find the volume of the given solid. Under the surface z = 7xy and above the triangle with vertices (1, 1), (4,1), and (1, 2) Use a double integral to find the volume of the indicated solid.
