Question

The sides of a right angled triangle forming the right angle are 5cm and 123cm.Find the radius of the circumcircle of the triangle.

Answer 1

In right angle triangle the diameter of circumcircle is equal to the lenght of the hypotenuse
so using pythagoros theorem
lenght of hypotenuse is
$\sqrt{5 { }^{2} + 123 {}^{2} } = \sqrt{15154 } = 123.10$
now the radius of circumcircle is the half of the hypotenuse
so the radius is 123.10/2=61.55

I think it is the ryte ans
