Unhide a worksheet:
There are several ways to hide or unhide a single worksheet. If you want to work with multiple worksheets then there are better methods than this.
For one or two worksheets, here are some examples.

Sheet1.Visible = xlSheetVisible
Sheets("Formulas").Visible = xlSheetVisible
Sheets(1).Visible = True

Sheets("Formulas").Visible = False
