Answer:
centre = (4, 0 ), radius = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 4)² + y² = 25 ← is in standard form
with (h, k) = (4, 0) and r = [tex]\sqrt{25}[/tex] = 5
Thus centre = (4, 0) and radius = 5
