$(35$ points$)$ You have a cylindrical silo $($radius $r)$ with a spherical cap roof $($radius $R).$ The cylindrical portion has a height of $H$ meters. The volume of the silo $(V_{\text{t}\text{o}\text{t}})$ can be obtained by adding the volume of the cylindrical part $(V_{cyl})$ to the volume of the spherical cap $(\{$:$V_{\text{c}\text{a}\text{p}}).$

$V_{cyl}=r^{2}H,V_{\text{c}\text{a}\text{p}}=\frac{1}{3}{h}^2(3R-h)$

where $h=R(1-cos)$ and $sin=\frac{r}{R}.$

The suface area of the silo $(S_{\text{t}\text{o}\text{t}})$ can be obtained by adding the surface areas of the cylindrical part $(S_{cyl})$ and spherical cap $(S_{\text{c}\text{a}\text{p}}).$

$S_{rvl}=2rH,S_{\text{r}\text{a}\text{n}}=2Rh$

Write an interactive function $M-$file to calculate the total volume and total surface area of a cylindrical silo for different values of $r,R,$ and $H.$ Your function should not accept any input arguments, but should ask the user interactively to enter values of $r,R,$ and $H$ of the silo. It should return two output arguments; i$.$e$.,$ the total volume $(V_{\text{t}\text{o}\text{t}})$ and surface area $(S_{\text{t}\text{o}\text{t}})$ of the silo. You can test your program to with $r=25m,R=35m,$ and $H=70m.$ Make sure that your results are displayed in short format either in scientific or fixed$-$point notation, whichever is more compact and convenient.
