Have you drawn this on a rough graph?  That is always a good place to start?

Have you done anything towards finding a solution?

I have hidden your other 2 questions for the moment.

Learn from this one and then try the others by yourself.

I will help you if you are prepared to help yourself.

Have you drawn that diagram jet?

almost

the formula is 

\((x-h)^2+(y-k)^2=r^2\qquad \text{where the centre is (h,k) and the radius is r}\\ \text{so can you spot your error?}\)
