please help with the MATLAB codes for these questions! thank you

The volume V of liquid in a hollow horizontal cylinder of radius r and length L is related to the depth of the liquid h by V=[x2cos1(rxh)(zh)2+hh2]L Develop an M-file to create a plot of volume versus depth. Here are the first few lines: Problem 3.22 Develop a function to produce an animation of a particle moving in a circle in Cartesian coordinates based on radial coordinates. Assume a constant radius, r, and allow the angle, , to increase from zero to 2 in equal increments. The function's first lines should be function phasor ( x,nt,nm ) I function to show the orbit of a phasor \& r= radius f nt= number of increments for theta 4nm = number of movies Test your function with phasor (1,256,10)
