Activity The equation of a circle centered at the origin with a radius of unit length is x2 + y2 = 1. This equation changes if the center of the circle is not

located at the origin or the radius is not of unit length. You will use the GeoGebra geometry tool to examine how the equation of a circle changes

as you move the center and change the radius. Go to equation of a circle C, and complete each step below. If you need help, follow these

instructions for using GeoGebra.

Question 1

Move the sliders to set the values of r, h, and k, and record at least three different sets of data. Also record the equations of the corresponding

circles.
