Is there a generic formula to express "to **know** how to do something"?

I know how to ask a question in the second person "How do you do something?",
e.g.

> How do you write "Yasuda" in kanji? 「やすだ」は漢字でどう書きますか。

I also know how to ask

> Can he write "Yasuda" in kanji? 彼は「やすだ」を漢字で書けますか。

but I am struggling to put it in the third person:

> Does he **know** how to write "Yasuda" in kanji?

How to say "to know how to do something"
It's あの人は「やすだ」は漢字でどうやって書くか知っていますか？, generally, to know how to do something is
どう（やって）…するか（を）知っている.
