This is a strange question – that I can’t figure out. I have a measuring tape – one of those that has a spring to wind it in automatically. When the tape is inside it is in a spiral shape. To make it easier we can say that the tape has a thickness of 1 unit. It also spirals from the center.

How would I find the Radius and Angle of a particular measurement? Also given the Radius and Angle – how would I find the measurement?

Thanks
