Chapter 2, Problem 23P

ThevolumeV of liquid in ahollow horizontal cylinder of radius r and length L is related to the depth of the liquid h by

$V=\left[r^2{\text{cos}}^{-1}\left(\frac{r-h}{r}\right)-\left(r-h\right)\sqrt{2rh-h^2}\right]L$

Develop a well-structured function to create a plot of volume versus depth. Test the program for $r=2\text{m and }L=5\text{m}$.
