please see following picture:
I am trying to find total area, so far- I was able to determine area of the semi-circles but I cannot figure out the area of the triangle in the middle.
The variables for the circle are L (arc length) and R (radius).
I found Area of each semi-circle is A= L*R/2
On a similar vein, this could happen, and so on.
I found that all I need to figure out is the length of one side as a function of R and L of the circle. All sides are equal since all circles are similarly shaped and mirror symmetrical (drawings may not show that exactly).
