an isosceles triangle those sides are 13 cm , 13 cm , 10 cm long inscribed in a circle . find the radius of the circle
a , b , c are sides of triangle , ad is the median , ad ^ 2 = ab ^ 2 - bd ^ 2 then ad = 12 , the centriod median divides into 2 : 1 ratio so 12 will be divide into 2 : 1 ratio so 8 is radius . so ans is 8 cm answer : a
add(divide(add(subtract(power(13, const_2), power(divide(10, const_2), const_2)), power(divide(10, const_2), const_2)), multiply(sqrt(subtract(power(13, const_2), power(divide(10, const_2), const_2))), const_2)), const_1)
