A rectangle with height 4 and width w contains three circles as in the diagram, all tangent to the rectangle and to each other. What is w?
+1008 Well then the largest circle must have diameter 4, since it's from one side to the other, and the other small ones, being equal, must have 4/2 diameters. 4+2 = 6
w = 6.
