Container A is a cylinder with a radius of 9 units and aIf a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line x = 1, what will be the resulting three-dimensional object? Cone Cylinder Sphere Pyramid height of 9 units. A right cone has been carved from its base and has a height of 9 units. Container B has the same radius as container A. Which statement derives the formula to find the volume of container B? container A is a right cylinder that has had a right cone subtracted from its base, container B is half of a sphere π(92)(9) − 1 over 3π(92)(9) 2[π(92)(9) − 1 over 3π(92)(9)] 1 over 3π(92)(9) − π(92)(9) 2[1 over 3π(92)(9) − π(92)(9)]4
