Answer by MathLover1(20850)   (Show Source):
You can put this solution on YOUR website! the circumference of a circle is 
a circle with center A( , ) and passes through B( , ) will have a radius  equal to distance between points A and B
| Solved by pluggable solver: Distance Formula |
The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (2, 3), we can say (x1, y1) = (2, 3)
So  , 
Since the second point is (4, 5), we can also say (x2, y2) = (4, 5)
So  , 
Put this all together to get: , , , and
--------------------------------------------------------------------------------------------
Now use the distance formula to find the distance between the two points (2, 3) and (4, 5)
 Plug in , , , and
==========================================================
Answer:
The distance between the two points (2, 3) and (4, 5) is exactly  units
The approximate distance between the two points is about 2.82842712474619 units
So again,
Exact Distance: units
Approximate Distance:  units

so, if we use the  , then will be
 or as decimal
