I need to find the equation of a circle with the center and one point provided> Please help.

OpenStudy (shadowfiend):

So first off, what is the equation of a basic circle with a radius \(r\)?

OpenStudy (anonymous):

Darn, you beat me to it.

OpenStudy (shadowfiend):

However, it looks like you already got help below, right? :)

OpenStudy (anonymous):

Um the x-h sq plus y-k sq equals r sq

OpenStudy (anonymous):

Well, you can find the radius by using the distance formula right?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

And you already know the center of the circle... so you can just plug your values into the formula you already provided.
