You are working as a software developer on NASA's Mars Explorer robotic rover project. You need to implement some code to compute the surface area of the $3$D$,$ tube$-$shaped part shown below: a cylinder of radius $$ and height $($in units centimeters$)$ with a hollowed$-$out center also in the shape of a cylinder with radius $$ and height $($also in cm$).$ Both the outside and the inside of the tube will need to be coated in a thin layer of gold, which is why we need to know its surface area. Write code that will compute and print the total surface area of the shape.
