## Description
|
||
|
|
<section id='description'>
|
||
|
|
Every triangle has a circumscribed circle that goes through the three vertices.
|
||
|
|
Consider all integer sided triangles for which the radius of the circumscribed circle is integral as well.
|
||
|
|
|
||
|
|
|
||
|
|
Let S(n) be the sum of the radii of the circumscribed circles of all such triangles for which the radius does not exceed n.
|
||
|
|
|
||
|
|
S(100)=4950 and S(1200)=1653605.
|
||
|
|
|
||
|
|
|
||
|
|
Find S(107).
