Answer:
3
Step-by-step explanation:
Triangle ABO is a right triangle, and so we can use the Pythagorean Theorem to find the radius, r:
r² + 6² = 7.5², or r² = 56.25 - 36 = 20.25
Taking the square root of both sides yields r = √20.25 = 4.5.
If the radius is 4.5, then subtracting this from 7.5 yields 3, the distance between point A and the rim of the circle.
The desired distance is 3 (Answer A).
