What is the measure of the radius of the circle that circumscribes a triangle whose sides measure 11, 60 and 61?  Choose the correct option:  A) 6.5  B) 12.5  C) 28  D) 30.5  E) 40
Some of pyhtagron triplets we need to keep it in mind.   Like {( 2,3,5) , ( 5,12,13) ,( 7, 24,25), ( 11, 60,61).   So now we know the triangle is an right angle triangle. The circle circumscribes the triangle.   The circumraduis of the circle that circumscribes the right angle triangle = hypotanse / 2 = 61 / 2= 
<gadget id="calculator">61 / 2</gadget>
<output>61/2 = around 30.5</output>
30.5   Ans. 30.5
<result>D</result>
