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
