5. In the figure there are infinitely many circles approaching the vertices <strong>of</strong> an equilateral triangle, eachcircle touching other circles and sides <strong>of</strong> the triangle. If the triangle has sides <strong>of</strong> length 1, find thetotal area occupied by the circles.It might help to complete the following table and then look for a pattern.Steph, height <strong>of</strong> thetriangles, length <strong>of</strong> the side<strong>of</strong> the triangles = 2 3 hr, radius <strong>of</strong> the A, area <strong>of</strong> the circlecircler = 3A = π r 26 s1 31 32 6π ⎜ ⎛ 3⎝ ⎠ ⎟⎞26 234
