(Section E consists of 3 CASE STUDY BASED questions of 4 marks each.)
A village is planning to dig a new well at a central location so that all surrounding houses are equidistant from it. The houses are located at points A (2,3), B (8,3) and C (5,7) on a coordinate grid representing the village map.
The village council wants to check whether these three houses lie in a straight line so that the well can be placed equidistantly. If they are not collinear, the council wants to find the midpoint of the line segment joining the two farthest houses to locate the well.
Answer the following questions:
(i) Calculate the distance between House A and House B. (1)
(ii) Calculate the distance between House B and House C. (1)
(iii) (A) Check whether the points A (2,3), B (8,3) and C (5,7) are collinear. (2)
(iii) (B) Identify the two farthest houses and give coordinates of the well. (2)
Design A: Brooch A is made with silver wire in the form of a circle with diameter 28 mm. The wire used for making 4 diameters which divide the circle into 8 equal parts.
Design B: Brooch B is made in two colours: Gold and silver. The outer part is made with Gold. The circumference of the silver part is 44 mm and the gold part is 3 mm wide everywhere.
(i) Find the total length of silver wire required to make design A. (1)
(ii) What is the area of each sector of the brooch in design A? (1)
(iii) (A) Find the area of the golden part in the brooch in design B. (2)
(iii) (B) A boy is playing with brooch B. He makes a revolution with it along its edge. How many complete revolutions must it take to cover $80\pi$ mm? (2)
