Answer:
(x + 2)² + (y - 5)² = 64
center = (-2 , 5)
x , y = point on the circle
64 = radius
Answer:
(-2,5)
diameter = 8, to get the radius divide it by 2
radius = 4
The standard equation for circle,
(x-h)²+ (y-k)² =r²
then substitute,
thus the equation of the circle is,
(x+2)² + (y-5)² = 4² or (x+2)² + (y-5)² = 16
