Question 458242: find the radius of the circle defined with these three points. (0,1),(8,1),(4,5)
Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 2 points have the same y, (0,1) and (8,1).
The 3rd point's x is 1/4 of the other 2, so the 1st 2 points are a diameter.
That makes the center (4,1) and the radius 4.
