God did not ask questions because He did not know the answers. He was not trying to figure out whether Adam was hiding in one or another of the trees. Later in the account of Cain and Abel when Cain was displeased that his offering was rejected, God asked him a series of questions.
So in both those incidences God asked a lot of questions.
In II Samuel 12:9, God asked David through Nathan, Why did you despise the word of the Lord? by doing what is evil in His eyes. In Isaiah 6:8, God asked Isaiah, Whom shall I send, and who will go for Us? And in Matthew 16:15, the Lord asked, Who do you say I am? The apostle John recorded many of Christ's questions as well. God asks questions to get us to face the situation. He asks us, we have to answer, and whatever we answer better be the truth. And then even if we answer the truth, often we have condemned ourselves, but that is one of the main reasons God asks questions - to get us to face the situation ourselves to more deeply realize what we have done.
This is what Jesus asks us when we have been trying to go it on our own, Have you been successful? Are you satisfied? Questions like that. He asks these questions through His inspired written Word so that we might recognize our hunger, need, failure, and need to turn to Him.
