I wanted to ask something about:「どっか行くかい」

Can someone explain how this sentence translated as: "Do you want to go somewhere?" (Like breaking it down for me)

Also does my translation accurate for daily use?

I think it translates literally to "Are you going somewhere?" which can be used in the same context as "Do you want to go somewhere".

Sound about right for daily use, yeah.

どっか　　　行く　　　かい

どこか（に）行きます　か
