Can anybody help???

Can somebody create a SolidWorks flat pattern to create a "rectangle to round duct" to the following dimensions for me as I am struggling to do this?

INTERNAL RECTANGLE LENGTH= 235mm

INTERNAL RECTANGLE WIDTH= 137mm

INTERNAL CIRCLE DIAMETER= 194mm

DUCT HEIGHT= 140mm

MATERIAL= MILD STEEL

MATERIAL THICKNESS= 3mm

Many thanks in advance!!!
