[plt-scheme] why no display in DrScheme beginning student level?

Here is another idea for flexibility:

(define TEST1 10)

;;areaDisc: number -> number
(define (areaDisc radius)
  (* radius radius 22/7))

"The area of a disc with a radius of " TEST1 "is" (areaDisc TEST1)

But, how can the result remain on one line?
