This is how you get (h,k) ie the centre further you can calculate the radius with distance formula since points on the circle are given
Then use centre radius form to find the final equation
(x-h)^2+(y-k)^2=r^2
P.S:Sry for not uploading the full solution cuz I think u can carry forward it easily(still mentioned the steps to be carried forward)
Hope it helps.......
