When doing geometry (keep in mind that I am only an eighth grader), I think that instead of writing an answer (random example) of 32 pi, I think the user should have to actually multiply by 3.14. Im only suggesting this because in school we learn to multiply by 3.14, and when you find the surface area of a cylinder, you have to add pi twice, and it gets extremely frusturating.
