30/360 = 3/36 = 1/12
so both the area and the volume include 1/12 times those of a complete cylinder of height 5 and radius 7 BUT add the rectangular sides of the wedge to the area so total area = (1/12) area of cylinder + 2 * r * h
a wedge is in shape of a secret of cylinder of radius 7cm and height 5cm with the angle of sector 30°.find the total surface area and volume of the wedge
