Question

If the sides of a triangle $ABC$ are $6,8,10$ units, then the radius of its circumcircle is

• A. $4$
• B. $3$
• C. $6$
• D. $5$

Answer 1

The correct option is D $5$

Given: $a=6,b=8,c=10$
From the length of sides we can see, that given triangle is a right angled
With hypotenuse $c=10$
Circumradius $:R=\frac{c}{2}$
$R=\frac{10}{2}=5$units
