Question

5. Find the center and radius of the circle with the given equation.

Answer 1

Answer:

A

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 + (y - 1)² = 25 ← is in standard form

with centre = (- 4, 1 ) and r = $\sqrt{25}$ = 5 → A
