[Woodcarver] Geometry question for the group

[J and C Lukens]

Unfortunately the formula is in error.....Circumference=d X
pi......diameter MULTIPLIED by Pi (3.1416)
                                                                            
                Area=r2 X pi....1/2diameter equals radius (r)....r2 is
radius squared
