Answer 2

Answer:

Let O is centre of circle.

Given

AB is diameter.

Then, OA = OB (Radius of Circle )

By Using Section Formula,

Coord. Of point O = { 26/2 , 24/2 }

= (13 ,12 )

Now, Radius OA = 11 Root 2.

[Find it by using Distance Formula ...

{Between OA or You can also find by

OB } ]

Hence, Radius of circle is 11 root 2 or 15.51 .
