I can't figure out this question and it is really getting on my nerves and ticking me off. Any help is appreciated.

A circle passes through the point \((12,0),\) and is tangent to the \(y\)-axis at the point \((0,3),\) as shown. Find the radius of the circle.

Thank you so much!

P.S: Sorry if I came off as a bit aggressive.
