Answer 4

1. Imagine slicing the onion from its edge to the center. Then, imagine taking all rings apart from the whole and stacking them up one by one in the order that they came off the onion. What shape would you have and why?


2. In terms of the circle, what is the height of this shape? Why? What is the length of the base? Why? (Use the definitions of a circle and a triangle, as well as formulas, to support your answer.)


3. How can you use this information to derive the formula for the area of a circle, A = πr2?
