Doing the Quiz instead of including another library for the PI value, i declared it as a float value, i had the doubt so i found the <cmath> library, in which you only have to write M_PI to show or use the PI value.
So i tried it in the Volume of a Cylinder program and it worked, in was easier than what i though.
Some post like this were using the <math.h> library but Ken told us to not use .h libraries so a friend told me about <cmath>.
Here´s how the program structure looks like:
