Question

Determining Whether a Point Lies on a Circle

Answer 1

Answer:

No

Step-by-step explanation:

If the center is at (0, 0) and if (0, -9) lies on the circle, then the radius must be 9.

In this case, the equation of this circle is

x^2 + y^2 = r^2 = 9^2.

Does (8, 717) satisfy this equation?  No.  717^2 would be far outside of the circle.  the distance from the center to the point  (8, 17) is not the same as the radius

Answer 2

Answer:

Yes, the distance from the origin to the point  

(8, ) is 9 units.
