Question

Find the center and radius of the circle.


can someone show me how to do this please

Answer 1

Answer:

You can see the center of the circle is at point (0,0).

The radius is the distance from (0,0) to any point along the circle.  IN this case we will use the point (4,0).  So the radius is basically 4.

Let me know if that helps.  If not I can try to explain more.
