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»

Step-by-step explanation:

Centre is the mid point of diameter->

(x1+x2)/2 , (y1+y2)/2

(1+5)/2 , (-2-6)/2)

6/2 , -8/2

(3, -4) is centre point

By distance formula

_____________

d= A0=radius= (x1-x2)²+(y1-y2)²

___________

= (1-3)²+(-2+4)²

________

= (-2)²+(2)²

_______

= 4+4

____

= 8

__

= 2 2 UNIT

Answer-

centre(3, -4)

radius= 2 2 units
