Question

Is he not known to you? change it to active voive

Answer 1

The answer would be

Do you know him ?

Reason behind it

We are given a sentence in passive thus its clear by

1) the verb form is in 3rd past participle

2) use of to and by are mostly done in passive

3) object usually comes before subject

Process of transformation

1) for present tense the form of verb should be  1st

2) try removing by and to from the sentence by bringing subject before object.

3) Make it simpler .
