Please do this in Matlab Thanks

Water flows from an inverted conical tank with circular orifice at the rate

$\frac{dx}{dt}=-0\mathrm{.}6r^2\sqrt[\phantom{2}]{2g}\frac{\sqrt[\phantom{2}]{x}}{A(x)},$

where $r$ is the radius of the orifice, $x$ is the height of the liguid level from the vertex of

the cone, and $A(x)$ is the area of the cross section of the tank $x$ units above the orifice.

Suppose $r=0\mathrm{.}1ft,g=32\mathrm{.}1f\frac{t}{s^2},$ and the tank has an initial water level of $8ft$ and

initial volume of $512(\frac{}{3})f{t}^3.$ Use the Euler's method of order four to find the following:

$($a$)$ The water level after $10$min with $h=20s$

$($b$)$ When the tank will be empty, to within $1$min
