2.2 110 B NOT TO SCALE In the diagram, AB is parallel to DE. Angle ABC = 110. Find angle BDE. Give a reason for your answer [2] 2.3 The diagram shows a quadrilateral with angle sizes 95, 82, x and 47 Find the value of x. [2] 470 NOT TO 950 SCALE 820 2.4 The diagram shows a cuboid. Find the total surface area of the cuboid. 8 cm [3] 4 cm 12 cm 2.5 8 cm The cake is made by putting a small cylinder of cake NOT TO 10 cm SCALE on top of a large cylinder of cake. The radius of the large cylinder is 15cm. The radius of the small cylinder 10 cm is 8cm. The height of each cylinder is 10cm. 15 cm (a) Calculate the total volume of the cake. [3] Use the value of it on your calculator and give the final answer rounded off to 1 decimal place. (b) Nora wraps a ribbon around the large cylinder. The ribbon is 4 cm longer than needed to go all the way around this cylinder. Calculate the length of this ribbon. Give the answer rounded off to the nearest whole number.
