Question

If A (1,-2) and B (5,-6) are the ends of the diameter of circle, then the radius and centre point of the circle​

Answer 1

Step-by-step explanation:

Let O(x,y) be the centre of a circle where A (1,-2) and B (5,-6) are the ends of the diameter of the circle.

Then,

Using mid-point formula

(x,y) = {(1+5)/2 , (-2-6)/2}

or, (x,y) = { 6/2, -8/2}

or, (x,y) = {3, -4)

Equating on both sides

x= 3

and, y= -4

Now,

Radius of circle = √(1-3)²+(-2+4)²

= √(-2)²+(2)²

= √(4+4)

= √8

= 2√2 units
