Question 1189798
<font color=black size=3>
Use the pythagorean theorem converse to find that
a^2 + b^2 = c^2
(3.3)^2+(5.6)^2 = (6.5)^2
is a true equation. Both sides simplify to 42.25


Therefore, this is a right triangle. 


For any right triangle, the circumscribed circle (aka circumcircle) has the hypotenuse as a diameter.
The radius is half the diameter, so c/2 = (6.5)/2 = 3.25 is the radius of the circumcircle.
