please give answer as Matlab script

Problem 1. ( 30 points) A horizontal surge drum has been inserted in the line to maintain a constant downstream flow rate even when the upstream flow rate varies. The drum has 5.0m of length L and 1.0m of radius r as shown below. The level of liquid in the drum h can be estimated by V=L[r2cos1(rrh)(rh)r2(rh)2] (a) The empty drum is charged with chloroform (density =1.48g/cm3 ) at a constant rate m =10kg min until the tank is half-full. How long should it take to reach that point? Write equations to be solved for this problem and submit a photocopy of the equations. Create a script to solve the equations. (b) Suppose the drum contains 5000kg of chloroform. What is the value of h at this point? (c) Plot V vs. h with 0.1m increment from the empty drum to the full drum. Using the data, plot dV/dh by the central different technique on the same plot. You may use a built-in function and the second y-axis if needed
