I'm in need of help calculating the area of the seven sections of a Venn Diagram.
I have three overlapping circles (A,B,and C) arranged in a Venn Diagram. Each circle overlaps exactly the same amount with equal radii, and all sides of the remaining circular triangles are of equal length (Equilateral Circular Triangle).
As with any overlapping Venn Diagram, there are three smaller, intersecting sections (AB,BC, CA,) and one middle section (ABC), which is slightly larger that the middle sections.
Each circle has the follow approximate measurements: Circumference: 31.42 Diameter: 10 Radius: 5 Area: 78.5
I found a document that contains the formula for such a problem, but I do not fully understand it. He says to treat the intersecting sections as triangles and the corners as circular elements. But when he gets into the actual formula, I am lost because he strikes off on tangents.
