Rita ,
Please let me know if my
translation is correct

What does Выступать mean in this context?

Hello Uly

Hi

Does it mean to make an appearance?

it maybe , have to come forward
or another variant

If the police are looking for you because you committed a crime, you may decide to “come forward“, or if you know who did it, you may decide to “come forward“ with information.

Ok I understand

There was a radio announcement about the President appearing in the night program.¿

Aha! Thank you, Tatiana!

why there was ....?

😉 А теперь напиши это по-английски. 😁

I don't understand it , because the tense is Future , am I right 😂

Предполагаю, что от Риты ожидают чего-то типа
The president was announced on the radio to appear...

"... would be..." Довуд, у нас это будущее называют Future-in-the-Past.

Ok 👍

And your translation is incorrect because it doesn’t have a subject and “move forward” is incorrect here.

Довуд, удалите, пожалуйста, свой перевод. И впредь посерьёзнее относитесь к переводам - Вы можете создать кому-нибудь проблему. :(

Ok
