Answer 1

Answer:

He was knew by me well........

Answer 2

Answer : Cannot be changed.

Explanation : This sentence cannot be changed into passive                                           voice. The verb (know) is a stative verb here.

So, this sentence cannot be changed into passive voice. If you think "He is known to me" is in passive form, then you need to know that "known" is an adjective here.
