A semicircle is inscribed in a rectangle. If the area of the semicircle is π, what's the area of the rectangle? My question yesterday was ... how could you draw the inscribed semicircle in a way that gives a rectangle of a very different (and larger) area?
My question today is, given the arrangement below, what points did I choose that had integer coordinates? I chose a larger semicircle - for convenience - how big was it?
