The sides of a triangle are 12, 35 and 37 cm. What is the circumradius of the triangle?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 18.5 cm.
Sides of the triangle are 12 cm , 35 cm, and 37 cm
As these numbers form a Pythogoreon triplet. So the triangle in the question is Right Angled Triangle.
Now, Circumradius = 1/2 × Hypotenuse [For a right angled triangle]
Hence,
Circumradius = 37/2 = 18.5 cm
