A dog is on a leash that is tied to a tree. The leash is 6 feet long. If the center of the tree could be considered the origin (0,0), the equation of the circle will be [tex](x)^2 + (y)^2 = 6^2[/tex]
What is the equation of the circle with radius r units, centered at (x,y)?
If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
A dog is on a leash that is tied to a tree. The leash is 6 feet long. If the center of the tree could be considered the origin (0,0),
we have r = 6
the equation of the circle will be
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
[tex](x-0)^2 + (y-0)^2 = r^2\\\\(x)^2 + (y)^2 = 6^2[/tex]
