In a triangle ABC, the lengths of the sides AB and AC equal 17.5 cm and 9 cm respectively. Let D be a point on the line segment BC such that AD is perpendicular to BC. If AD=3 cm, then what is the radius (in cm) of the circle circumscribing the triangle ABC?
Let the sides be a = AB, b = AC, e = BC
⇒A (ΔABC) =
R = = cm²
