Given:
Richard and Linda enjoy visiting Hilton Head Island, South Carolina.
The distance from their home to Hilton Head is 870 miles.
So, the drive takes them 2 days.
<u>Richard and Linda travel four times as far the first day as they do the second day.</u>

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 =
=
= = 8 → A
