I actually skipped a transformation in the end, so this is what it
should have been:

;; Let style
(define (pyth-ls x y k)
    (let ([x2 (* x x)])
      (let ([y2 (* y y)])
        (let ([x2py2 (+ x2 y2)])
          (let ([result (sqrt x2py2)])
           (k result))))))

; CPS Style
(define (pyth-cps x y k)
   ((λ (x2)
      ((λ (y2)
         ((λ (x2py2)
            ((λ (result)
                (k result)) (sqrt x2py2))) (+ x2 y2))) (* y y))) (* x x)))
