    Well the volume of a cylinder is \[\pi * r ^{2} * h\]

    By any chance, do those answer choices have a "pi" in them?

    Well then it's not A. You have to do pi * r^2 * h (which is 12^2 * 13 * pi)

    so instead of guessing look at the drawing what is r? What is r^2 (r * r)? What is h? Use the formula given above

    it is a simple multiplication pi * r *r * h put the values for that into your calculator. If you keep messing up ,then practice until you don't

    Well, as @MrNood said, you have to identify the parts of the cylinder and then use the formula. Here is a diagram for the parts of a cylinder. http://www.numberempire.com/shapes/images/cylinder_main.png
