Question 1 The volume of the solid under the surface z = cos(x² + y²) over the region D = {(x, y) | 25 ≤ x² + y² ≤ 100} in polar form is where A = B = C = 0 D= 2π E = ● Question 2 5 10 The volume of the solid is Mass=T cos (2) Question 3 ["T" D E dodr Find the mass of the solid bounded below by the circular cone z = √√² + y² and above by the hemisphere z = √5.5²-2² - y² if the density is f(x, y, z) = x² + y² + ₂². V 1 pt 1 Details x-coordinate of the center of mass= y-coordinate of the center of mass y = z-coordinate of the center of mass z = 1 pt 1 Details 1 pt 1 Details Find the center of mass of the solid S bounded by the paraboloid z = 4x² + 4y² and the plane z = 12. Assume the density is constant. Hint: Think about the shape before calculating - you can greatly reduce the number of calculations to be done.
