+28 Find the height,h, of the diagram if each circle has a radius of 2cm
+129852 If we connect the centers of the bottom three circles, we will form an equilatersl triangle with sides = 4
The height of this triangle = sqrt (3) / 2 * side length
And, by symmetry, we have two of these triangles......so their combined heights = sqrt (3) * side length =
4sqrt (3) cm
And the other part of the total height is formed by 2 radii of a circle = 2 * 2 = 4 cm
So....the total height = 4 ( sqrt (3) + 1) cm ≈ 10.928 cm
