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
