Question

Identify the center and radius of the circle.

(x + 10)^2 + (y – 4)^2 = 4

O Center: (-10, 4)
Radius: 2

Center: (-10, 4)
Radius: 4

Center: (10,-4)
Radius: 4

Center: (10,-4)
Radius: 2​

Answer 1

first option

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 + 10)² + (y - 4)² = 4 ← is in standard form

with (h, k) = (- 10, 4 ) and r =
`√(4)` = 2

Thus

centre = (- 10, 4 ) and radius = 2
