<h3>
Answer:</h3>
1) Radius: 2√7
2) Center: (10, 5)
3) Circumference: 33.25
<h3>
Explanation:</h3>
Circle formulae:
where (h, k) is the center coordinates, r is radius
Rewrite the equation into standard form:
- (x-(10))² + (x - (5))² = (√28)²
Identify following of the circle:
- h = 10, k = 5, radius = √28 = 2√7
In order to find the Circumference of circle:
- Use the formula: 2π(radius)
radius: 2√7
- Circumference: 2π(2√7) = (4√7)π = 33.2475 = 33.25
It would be 14.68 have a nice day
Get more specific. Don't look at days know, look at hours. Since there are 24 hours in a day, and there are 17 days, do 17*24 to get a total of 408 hours. Divide this by 2 to get 204 hours (or 8 hours 30 minutes) for each person's trip.

You know that all of the triangles are congruent, so you only have to find the area of one and then multiply it by four. So you would multiply 5 by 7 and get 35. The divide that my two to get 17.5, which is the area of the triangles. Then you would multiply that by four and get 140, which is the area of the figure
