B) What is the area of sheet metal used in the drum if it has an open top? ii) The shape of the cross-sectional area of an extrusion is a sector of a circle subtending an angle of 50 degrees. The circle radius is 25mm. What is the volume of the extrusion if it is 3.2m long in mm-cubed and in m-cubed? If the extrusion is cut into 50mm long sections, determine the surface area of each section. Please show workings.
