A circle of radius x cm is inscribed in an equilateral triangle and is tangent at three points. Three smaller circles are inscribed so that they are each tangent to two sides of the triangle and to the larger circle. The process is continued with circles of ever decreasing diameters. What is the sum of the areas of all the circles so drawn??

1) (3pi x^2)/ 2
2) (3pi x^2)
3) (5pi x^2)/ 2
4) (2pi x^2)
