A: How to calculate remaining volume of a wire spool After I wrote up the question, I think the answer just hit me. Calculate the area of three circles: (was going to say cylindars, but I don't think that axis matters) a) the minimum/empty diameter b) the maximum/full diameter c) the current media diameter Then: b-a = the starting area of med...

When I pick one I need to know that it likely has enough remaining for my print job. How can I calculate the (approximate) volume remaining of a spooled wire, given the diameter of the core/center of... (more) |

Missing a solution: Are A and B always equal if A-B=0 I just came across this problem on an online learning app: 4x(5−x)−12(5−x)+100=100 I tried to solve it by subtracting 100 from each side then inferring if something minus something else equals zero then those two things must be equal. 4x(5−x)=12(5−x) Divide both sides by (5-x) and x must ...
