Removing "Recent posts, comments, archives,ect" from page

I’m using WordPress to host a basic website for a small non-profit.

I would like to remove the “Recent posts, recent comments, archives, categories and meta” tabs to the right of all the pages because I won’t be using it for posting, just presenting information about the non-profit.

Is there a way to do this without coding? If there is, please let me know, and if there’s not, any suggestions in tackling the code part of it for someone without any coding knowledge?

Thanks and best!!
