Answer:

Step-by-step explanation:
The equation of a circle:

(h, k) - center
r - radius
We have the center (4, -3) and the point on the circle (9, -3).
The length of radius is equal to the distance between a center and an any point on a circle.
The formula of a distance between two points:

Susbtitute:

The center (3, 7) → h = 3, k = 7.
Finally we have:

Acute is one way struggling to find any more
Do 55,427 divided by 67,103 which is 0.825998838 then multiply that by 100 to get 82.5998838 then round up to the nearest tenth to get 83 percent
