Question 1049375: Let the points (-1, -2) and (-1, 3) be the endpoints of a circle. Find the length of the diameter of the circle.
Answer by MathLover1(20850)   (Show Source):
You can put this solution on YOUR website! if the points ( , ) and (,  ) be the endpoints of a circle-> there is no such a notion "the endpoints of a circle"
it could be two points on a circle opposite to each other, or  of the 
if so, than the length of the diameter of the circle is equal to distance between these two points
| Solved by pluggable solver: Distance Formula |
The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (-1, -2), we can say (x1, y1) = (-1, -2)
So  , 
Since the second point is (-1, 3), we can also say (x2, y2) = (-1, 3)
So  , 
Put this all together to get: , , , and
--------------------------------------------------------------------------------------------
Now use the distance formula to find the distance between the two points (-1, -2) and (-1, 3)
 Plug in , , , and
==========================================================
Answer:
The distance between the two points (-1, -2) and (-1, 3) is exactly 5 units

so, the diameter of the circle is
