Question

The equation of a circle is (x-2)2+(y-6)2=25. What is the radius of the circle?

Answer 1

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 = $\sqrt{25}$ = 5
