1. 1650 / 55 = 330 / 11 = 30
2. 5634 / 18 = 939 / 3 = 313
3. 6440 / 28 = 920 / 4 = 230
4. 5256 / 52 = 2628 / 26 = 1314 / 13 = 101.07
5. 1955 / 85 = 391 / 17 = 23

Answer:

Step-by-step explanation:
We want to write the equation of a circle with a diameter of 10 units centered on (-2, 1).
Recall that the equation of a circle has the standard form:

Where (<em>h, k</em>) is the center and <em>r</em> is the radius.
Since our diameter is 10, our radius is 5.
And since the center is at (-2, 1), <em>h</em> = -2 and <em>k</em> = 1.
Substitute:

And simplify. Hence, our equation is:

The answer is 0.000000099.
Hope this helps! :D
