OpenStudy (book):

I came up with this so far.

OpenStudy (3mar):

Could I help you?

OpenStudy (book):

Yes

OpenStudy (3mar):

Thank you.

OpenStudy (3mar):

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..

OpenStudy (3mar):

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

OpenStudy (book):

Ya thats whats i was thinking... ty for your help!

OpenStudy (mathstudent55):

For any circle, the diameter is always twice the radius.

OpenStudy (book):

ty guys

OpenStudy (3mar):

You are welcome! Any Help... Any Time...

OpenStudy (mathstudent55):

Your graph is a bit inaccurate.

OpenStudy (mathstudent55):

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.

OpenStudy (book):

Could u draw me it?

OpenStudy (book):

OpenStudy (book):

I tried to make mine look like this
