A triangle is inscribed in a circle - what’s the radius?

[@garrington120]

WRONG 13 x 13 + 7x7 = 218 root is 14.76482 divide by 2 is 7.38241

[@cowboyteacher5243]

Yes 14.76
I wrote 14.6 and Forgot to write 7 in between.

[@pauleveritt6589]

The answer is 7.38 . The square root of 13 squared plus 7 squared divided by 2 = 7.38.

[@cowboyteacher5243]

Correct

[@gunnyh3837]

Only if it is a right triangle.

[@Wanarunna]

where in the question does it stipulate that one side of the triangle passes through the center of the circle?

[@eddarby469]

He stipulated the long line passed through the center.

[@jimotto9361]

How do we know this is a right triangle?

[@davidspahn7184]

The angle formed by any point on a circle and 2 end points of a diameter is always 90 degrees (assuming, of course, that the first point is not also one of the end points of the diameter, because that wouldn't form a triangle).

[@harrymatabal8448]

Me know you David how do you know that the endpoints are on the diameter. Think before you ink. So if the 2 end points were lower down then it is the diameter. Thanks for educating me

[@davidspahn7184]

@@harrymatabal8448 Because he says, at 0:45, "This line is passing through the center of the circle," and then proceeds to say, "This is the diameter." Take your own advice, internet troll.

[@harrymatabal8448]

I can't even see the diameter let alone the radius. With due respect how do we know the bottom line is the diameter.
Maybe I am stupid

[@cowboyteacher5243]

I'm saying in a video that the line is passing through the center of the circle.
