Subject: Access returned value in a string?

Can  I access the returned value in a string?

eg
questions = [
"A slide is placed #{rand(3..15)} cm to the left of a lens.",
...
]

puts questions[0]
>>A slide is placed 12 cm to the left of a lens.

I need to pass 12 to a function.  Do I have  to extract  it from the
string or is it stored somewhere I can access it?
