Answer:
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 - 2)² + (y - 6)² = 25 ← is in standard form
with r² = 25 ( take the square root of both sides )
r = [tex]\sqrt{25}[/tex] = 5
