Find The Height Math Question

​Find the height, h, of the diagram if each circle has a radius of 12 cm.

h ≈ 65.569 cm 

We  can construct  two  equilateral  triangles  with sides of 24 cm   by  joining  the centers of  the circles

The  height  of  one  of  these triangles  =  (1//2) side length * sqrt (3)  = 12sqrt (3)

So....the height of the the  figure = 

Height  of two equilateral triangles  + diameter  of a circle  = 

2 * 12sqrt (3)  +  24   =

24  ( 1 +sqrt (3))  ≈   65.57   cm
