PLEASE HELP I REALLY NEED HELP.

Each of the three circles in the figure below is externally tangent to the other two, and each side of the triangle is tangent to two of the circles. If each circle has radius three, then find the perimeter of the triangle.

The figure is basically an equaliteral triangle. Inside there are three circles of the same size and are congruent. The radius of each circle is 3.

PLEASE HELP!!
