Question

What is the center of the circle:What is the center of the circle: (x+1)^2+(y-12)^2=25

1. 25
2. (1, -12)
3. 5
4. (-1, 12)

Answer 1

option 4

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 + 1)² + (y - 12)² = 25 ← is in standard form

with centre = (- 1, 12 ) and radius =
`√(25)` = 5
