To Geometry students: If you were to approximate each sector with a parallelogram, what would be the dimensions and area of such parallelogram?
To Calculus students: Make n large. If you were to estimate the total area by approximating every thin sector with a rectangle (like in Riemann sums) what would be the width of such rectangle?
