Developing Area of a Circle

The sectors from the circle are rearranged and placed side by side alternating placement of the vertex point. Move the sector slider to increase the number of sectors. When the sectors are placed together, what do they begin to form as the number of sectors increase? What value does the length of of the sectors approach? What is the height of the sectors? Using the show length box will turn on the display of the segment values.
