Question

What is the circumradius of a triangle whose sides are 7, 24 and 25 respectively?

Options:

A . 18

B . 12.5

C . 12

D . 14

Answer: Option B
:
B
Option b
It’s important that we note that it is a Pythagoras triplet
7

^{2}

= 25

^{2}

+24

^{2}

Now,
In a right-angled triangle, the median to the hypotenuse is half the hypotenuse and is also the circum radius of the triangle.
As the hypotenuse is 25, the circum radius is 12.5
