1. The problem statement, all variables and given/known data A factory has a machine which bends wire at a rate of 4 unit(s) of curvature per second. How long does it take to bend a straight wire into a circle of radius 8? My professor likes to give us things we've never seen before on our weekend quizzes. The above is one such problem. All that I can get from that problem statement is that k(t) must equal 4? Can anyone kind try and explain what they are actually asking?
