Okay here it is ill brk it down for u

AB= 8
CD= 8

AD=20 and AB + CD = 16 u have 4 left

So 2 goes in one of the circles and the other 2 in the other i dunno how to show u that, like where point B is to the end of the diameter is 2 and from C to the beginning of the diameter is 2. And now u have a complete 20. TO get the radious we know that AB = 8 from B to the end of the diameter is 2 and that will = 10 and the beginning of the circle from point A to the beginning is also 2. THe diameter = 12 and 6 is ur answer! not 5

One clue is that the four line segments are of EQUAL length and perpendicular.
