Hearsay
No, since the question presumes the evidence is hearsay; therefore it is inadmissible even if the witness had the highest degree of credibility. There are many exceptions to the hearsay rule and many instances where an out of court statement seems to be inadmissible hearsay but is not (i.e. non hearsay hearsay), that it serves no purpose to provide facts that would allow the statement to be used at trial. If the question posed more facts than just the statement that the evidence is hearsay, they would show whether the statement is admissible under an exception or as non hearsay hearsay. Once the statement is admitted as evidence it would be up to the jury to determine if the witness is believable.
Evidence based on hearsay.
Hearsay is not evidence, the court rules will not allow it to be heard. As you have stated in your question it is, by definition, INADMISSIBLE.
Hearsay (information obtained second-hand, such as something overheard) is, absent certain conditions, inadmissible as evidence at trial. However, there are numerous exceptions to the hearsay rule. It's impossible to answer your question without knowing the facts of the case and the hearsay rules in the jurisdiction where the case is being heard.

Hearsay evidence.
No
In Stroud v. Golson, the court found that the hearsay evidence presented was inadmissible because it did not fall within any of the exceptions to the hearsay rule. The court emphasized the importance of ensuring that only reliable and trustworthy evidence is used in legal proceedings to protect the rights of the parties involved.
The Federal Rules of Evidence generally exclude hearsay statements unless they fall within an exception. Hearsay is an out-of-court statement offered to prove the truth of the matter asserted, and it is generally considered unreliable evidence due to its potential for distortion or inaccuracy.
