For the general equation of the circle:
radius r=3
center=(2,-3)
Satisfied?
OpenStudy (book):
So for the question i have, the radius would be 4 and the center would be (2.-3)?
OpenStudy (book):
Doesn't there need to be more coordinates or is it just 1 pair
OpenStudy (3mar):
No, man
the radius would be 3, as 9 =3^2
OpenStudy (book):
Oh! i meant to put 3..

Ok
OpenStudy (book):
Whats the diameter then?
OpenStudy (3mar):
Why do you need the diameter?
OpenStudy (book):
OpenStudy (3mar):
The diameter is always the twice of the radius.
r=3
d=6

You know exactly where the center is.
Plot the center.
You know the radius is 3, so from the center, measure 3 up, 3 down, 3 right, and 3 left.
Plot those 4 points.
The circle must go through those 4 points.
