Answer:
EASY!
Step-by-step explanation:
So I have not done this type of problem before, but I can help!
So what we need to do is find the distance between those two points, and that's are radius! (because any point on a circle is equidistant, or the same distance away from the center).
To do this, we need to use Pythagorean Theorem:
It's a theorem that states that sum of the squares of the leg's of a right triangle is equal to the square of the hypotenuse.
Here's a little picture if you don't know what I'm talking about:
(the one that is attached to this answer)
So, the radius we are looking for is C.
Now, imagine a right triangle were from one point it draws a horizontal line and from the other endpoint, we draw a vertical line that intersects the horizontal line, and that's our triangle.
Now we also know the 'legs' of the triangle with the info that: 9-0=9, 5-0=5
And we know that A and B are 9 and 5(order does not matter).
So, time to solve!
[tex]9^{2} +5^{2} =C^{2}\\\sqrt{106} =C\\[/tex]
Hope this helps!
P.S. Stay Safe!
