It's just the perimeter of a semicircle with radius 4. The angles are each 60 degrees = pi/3, so 3 of them is pi. s = r{theta} = 4pi ~ 12.5663706 cm.

@duffytoler: i know that your previous result is in term of unit circle and disregard what you think a unit circle is, the formula is still wrong. First, what do you think is the area of the triangle ? Second, add your result with 0.5*pi*(4)^2, corresponds to the area of 3 pieces of the circle. Do you get the area of the triangle ?
