$x$

A cylindrical part $($diameter $D,$ height $H)$ has a square cutout $($side $s,$ height $h).$ The volume and surface area of this part can be calculated as follows.

$V=\frac{D^{2}H}{4}-s^{2}h$

$A=D(H+\frac{D}{2})+4sh$

Write a program to calculate both of these values and display them to the screen, using $D=15mm,H=12\mathrm{.}5mm,s=8mm,h=4\mathrm{.}25mm.$

Store the volume in a variable named Vol and the surface area in a variable named SA$.$
