Sorry if this is a silly question.  

I did the following sequence of commands.  I closed the scatter as soon
as it opened.  No other commands.  

Why does r(mean) go away after you use it in the scatter with the
formatting extended function?

. sysuse auto, clear
(1978 Automobile Data)

. quietly summ length

. di `r(mean)'
187.93243

.  di `: di %9.1f `r(mean)''
187.9

.  di `: di %9.1f `r(mean)''
187.9

. twoway scatter length mpg, text(200 35 "The mean of length is:`: di
%2.1f `r(mean)''")

.  di `: di %9.1f `r(mean)''


. di `r(mean)'


.

No. You should try 

` : di %9.1f `r(mean)'' 

See help extended_fcn. 

Tip: I would go `: di %2.1f `r(mean)'' even 
if you are sure that format is too restrictive. 
You're likely to be wrong, as Stata will stretch the space to 
avoid damage. However, with %9.1f you are likely to get the ugly 
spaces that are a consequence of what you asked
for.
