A frustum is formed when a plane parallel to a cone’s base cuts off the upper portion as shown. Which expression represents the volume, in cubic units, of the frustum? π(7.52)(11) – π(3.52)(8)

A frustum is formed when a plane parallel to a cone’s base cuts off the upper portion as shown. Which expression represents the volume, in cubic units, of the frustum? π(7.52)(11) – π(3.52)(8) π(7.52)(11) + π(3.52)(8) π(7.52)(19) – π(3.52)(8) π(7.52)(19) + π(3.52)(8)
