Using a new MATLAB script, show how the inner radius of the tube changes as a function to the outer diameter. For this analysis, use a diameter of $3$ inches for the solid cylinder and vary the outer tube diameter $3\mathrm{.}2$ to $5$ inches. You must select $($estimate$/$guess$)$ the proper range here in order to produce the desired plot. Finally, using the graph you just developed, estimate the inner diameter of the tube that has an outer diameter of $4$ inches.
