Answer:

The answer to your question is: The second option is correct.

Explanation:

Data

Center (-2, 0)

Point (-2, 4)

Second point = (1, √7)

Formula

d = √(x2 - x1)² + (y2 - y1)²

Radius

d = √(-2 +2)² + (4 - 0)²

d = √ 0² + 4²

d = √ 16

d = 4

Distance from center to (1, √7)

d = √(1 + 2)² + (√7 - 0)²

d = √ 3³ + √7²

d = √ 9 + 7

d = √ 16

d = 4

Both distances measure the same, so (1, √7) lies on the circle
