    Finding Volume of a cylinder without height or given the hypotenuse



    One of the questions in my chemistry lab is asking to find the volume of a cylinder without the height provided. I would use Pythagorean's Theorem using the base (r * 2) and was given the hypotenuse.

    I'm stuck with the mass of the cylinder and its radius. I'm not sure if the professor is that involved with applying physics where weight = mass * Earth's gravity, but this seems irrelevant. Any suggestions?

    Seriously this is a college level chemistry question? What retarded chemistry proff is not using metric units and makes you do conversions?

    Uhm, What metal? Their densities and volumes differ so that would affect how tall the cylinder is? Right?

    Is the metal specified in the earlier questions?

    The correct answer is "This is a bullshit question".

    Yeah, aluminum vs. Gold would make quite the difference.

    If the actual metal is provided, a numerical answer is pretty easy. If not, a function can still be easily generated, and may be well be sufficient for an answer.

    Density = mass / volume. You have the weight, so you can get the mass assuming Earth gravity, and the volume formula is given, so it becomes density = mass / (pi * radius ^ 2 * height).

    Dude, your instructor is a sadistic ass and you need to find someone else in that program to study under. Ah, Calculus, the reason I became a History major...

    Does "made of your pure metal" refer to something in a previous question on the same worksheet? If you have the density this seems straightforward. If you have no way of getting the density, then your answer would be a function of the density, e.g. Q / density.

    I have a feeling the previous questions would lead me to know the specific density of which “pure metal” the questions refers to. I’ll figure it out in class and report back.

    Thanks all, I knew using my Post 9-11 Bill benefits towards B.A. in Gender and Women Studies is worth it.

    Well, can't you get the radius if you have the circumference of the circle by multiplying it by pi to get the diameter and using half of that?
