Write a python code.

Write a python code for the problem below.

Consider a cylindrical gasoline storage tank of diameter, $D=3m,$ and length, $L=6m,$ as shown in figure below:

The equation for the volume, V $,$ of the fluid in the tank filled to a depth, h $,$ is given by:

$V(h)=2*L*{\displaystyle \underset{0}{\overset{h}{}}}\sqrt[\phantom{2}]{(\frac{D}{2}{)}^2-(x-\frac{D}{2}{)}^2}dx$

Determine the depth of the fluid, h$,$ when the tank contains $15,000$ gallons of gasoline using any method discussed in class. Verify your answers graphically.
