A search and rescue helicopter shines a light down from a vertical height of 50 metres as shown below. The circular area of light it creates on the ground has a diameter of 10 metres. Question 1 The helicopter is elevated an additional 15 metres away from the ground. The diameter of the circular area of light on the ground is now closest to A. 8 m B. 13 m C. 15 m D. 20 m E. 25 m Question 2 The helicopter moves to a height so that the diameter of the circular area increases from 10 metres to 40 metres. The area of the circular light is now A. four times what it was before. B. eight times what it was before. C. sixteen times what is was before. D. thirty-two times what is was before. E. sixty-four times what it was before. Further Mathematics Unit 4 Page 2 Week 2 SEND Work Question 3 The value of x in the following figure is 3.

The design of the swimming pool is shown in the diagram below. The pool has two sections: one section has a flat base, while the other section has a sloping base. From the shallow end of the pool, the first 25 metres of the pool has a constant depth of 0.9 metres. Halfway along the length of the pool, the depth begins to increase at a constant rate, reaching a maximum depth of 2.2 metres. (a) Name the shape of the quadrilateral ABCF. ___________________________________________ (b) Calculate the distance EI. Write your answer in metres, correct to two decimal places. [Hint: draw out the triangle that is involved in calculating EI]. (c) Calculate the area of the side of the pool bound by ABCDEFA. Write your answer in square metres, correct to one decimal place. Further Mathematics Unit 4 Page 5 Week 2 SEND Work (d) Using your answer to part c., find the volume of water required to fill the pool. Write your answer correct to the nearest cubic metre. (e) The sloping section of the base of the pool bound by the rectangle BCGH is painted first and that section of the pool is filled before the flat section of the base is painted. Calculate the volume of water required to fill the section of the pool with the sloping base, up to the level of the flat base. Write your answer correct to the nearest cubic metre. [Hint:Visualise the section that will be filled up with water and draw the 3-D diagram that represents it] Question 9 The top two-metre section of a five-metre high cone is removed. Calculate the percentage of the total volume of the remaining (bottom) part.
