The function consumes a circle structure and draws the corresponding circle on the screen. Use (start 300 300) to create the canvas befo...Alt234 Stuck on another question 22 28 (10/20/2010 11:50:32 PM) comp.lang.schemeHere i'm using the draw.ss teachpack, to create a function for draw-a- circle. Now i know that the default built-in-function is (draw-circle (center radius color)), where 'center' is a posn structure, radius is...Alt234 Can someone test this function out for me? 5 32 (10/19/2010 12:08:38 PM) comp.lang.schemeExercise 6.3.3.
