From the circumradius formula, R = 37/2.

In triangle JKL, we have JK = JL = 25 and KL = 30. Find the circumradius.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Semiperimeter   s = 40 

 

Triangle area     A = 300          

 

Inradius    r = A / s     r = 7.5

 

Circumradius   R = (abc) / 4rs     R = 15 5/8

Here is visual confirmation that R = 155/is correct.
