Consider the solid whose base is the region bounded by the x-axis, y = x, and y=-4x + 5. Find the volume of the solid if the slices perpendicular to the y-axis are rectangles with height sin(y). Give the exact volume below in the form A + B sin(C) where A, B and C are constants to be determined. Click on the symbol for the equation editor to enter in math mode. b a sin (a) ∞ a

Find the volume of the solid whose base is the circle x² + y² = 49 and the cross sections perpendicular to the x-axis are triangles whose height and base are equal. Find the area of the vertical cross section A at the level x = 4. A = V
