Answer:
Equation of the circle   (x-3)²+(y-5)²=(6.4)² 
                              x² -6x +9 +y² -10y +25 = 40.96
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given endpoints of diameter P(−2, 1) and Q(8, 9)
Centre of circle = midpoint of diameter
                    Centre = 
                Centre (h, k) = (3 , 5)
<u><em>Step(ii):-</em></u>
The distance of two end points 
PQ = 

PQ = √164 = 12.8 
Diameter    d = 2r
                  radius r = d/2
                 Radius r = 6.4
<u><em>Final answer:-</em></u>
Equation of the circle  
                     (x-h)²+(y-k)² = r²
                    (x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
x² -6x  +y² -10y  = 40.96-34
x² -6x  +y² -10y -7= 0
