The volume, Vm³, of liquid in a container is given by V = (3h² + 4) - 8, where h m is the depth of the liquid. Which of the following is/are true? Liquid is leaking from the container. It is observed that, when the depth of the liquid is 1 m, the depth is decreasing at a rate of 0.5 m per hour. The rate at which the volume of liquid in the container is decreasing at the instant when the depth is 1 m is 4.5√7. dV 6h√3h² +4. dh The value of at h = 1 m is 9√√7. Non of the above is true. d²V 9h√3h² +4. dh² = = M
