Answer:

A

Step-by-step explanation:

The distance from the centre to a point on the circle is the radius.

Calculate radius r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (5, - 2)

r = \sqrt{(5+3)^2+(-2+2)^2}

  = \sqrt{8^2+0^2}

  = \sqrt{64} = 8 → A
